For example, a liquid crystal optical element is proposed in which at least one substrate surface of the substrate contacted by the liquid crystal resin composite is covered by a thin film having substantially uniform wettability to the unhardened mixture used to form the liquid crystal resin composite (For example, refer to Patent Document 1). The substrate of Patent Document 1 is formed by forming ITO (Indium Tin Oxides) on a glass plate, and then depositing SiO 2 with a thickness of 60 nm on the ITO to form a thin film. Furthermore, in Patent Document 1, since the unhardened mixed liquid exhibits substantially uniform wettability on the entire substrate surface, it is difficult for bubbles to remain on the substrate surface.

另一方面,形成無機層4後經過80小時以上後之無機層4之水接觸角θ1係相對於剛形成無機層4後之水接觸角θ0發生變化。具體而言,形成無機層4後經過80小時以上後之水接觸角θ1相對於剛形成無機層4後之水接觸角θ0之比(θ1/θ0)例如為0.3以上,較佳為0.5以上,更佳為1.0以上,進而較佳為2.0以上,又,例如未達4.5,較佳為4.0以下,更佳為3.5以下,進而較佳為3.0以下,尤佳為未達3.0。若上述比為上述上限以下,則可抑制形成無機層4後經過80小時以上後之無機層4之水接觸角θ1產生偏差。 藉此,獲得依序具備透光性基材2、透光性導電層3及無機層4之透光性導電膜1。 透光性導電膜1之總厚度例如為2 μm以上,較佳為20 μm以上,又,例如為300 μm以下,較佳為200 μm以下,更佳為150 μm以下。 該透光性導電膜1係產業上可利用之器件。 5-4.步驟(4) 透光性導電膜1之製造方法進而於步驟(3)之後,包括蝕刻透光性導電層3之步驟(4)。 於步驟(4)中,於步驟(3)之後,蝕刻透光性導電層3。具體而言,將透光性導電層3與無機層4一併蝕刻,將透光性導電層3及無機層4圖案化為特定形狀。 作為蝕刻液,只要為可溶解透光性導電層3之溶液則並無特別限定,例如可列舉:硝酸、磷酸、乙酸、鹽酸、硫酸、草酸及該等之混合液等。

6.調光膜之製造方法 其次,參照圖2對使用上述透光性導電膜1而製造調光膜20之方法進行說明。 該方法如圖2所示,包括:步驟(6),其係製造2個上述透光性導電膜1;及步驟(7),其係藉由2個透光性導電膜1夾持調光功能層5。 6-1.步驟(6) 於步驟(6)中,製造2個上述透光性導電膜1。再者,亦可對1個透光性導電膜1進行切斷加工,準備2個透光性導電膜1。 2個透光性導電膜1為第1透光性導電膜1A及第2透光性導電膜1B。 6-2.步驟(7) 步驟(7)係於步驟(6)之後實施。於步驟(7)中,於第1透光性導電膜1A中之無機層4之上表面(表面)上,例如藉由濕式而形成調光功能層5。 調光功能層5例如為電致變色層或液晶層等,較佳為液晶層。 於該步驟(7)中,例如,將包含液晶組合物之溶液塗佈於第1透光性導電膜1A中之無機層4之上表面。液晶組合物可列舉溶液中所包含之公知者,例如可列舉日本專利特開平8-194209號公報記載之液晶分散樹脂。 繼而,以第2透光性導電膜1B之無機層4與塗膜之表面接觸之方式將第2透光性導電膜1B積層於塗膜之表面。藉此,藉由2個透光性導電膜1、即第1透光性導電膜1A及第2透光性導電膜1B而夾持塗膜。 其後,對塗膜實施適當之處理(於液晶組合物包含紫外線硬化型組合物之情形時,紫外線照射),形成調光功能層5。調光功能層5係形成於第1透光性導電膜1A之無機層4與第2透光性導電膜1B之無機層4之間。 藉此,獲得依序具備第1透光性導電膜1A、調光功能層5及第2透光性導電膜1B之調光膜20。 而且,調光膜20係於具備電源(未圖示)、控制裝置(未圖示)等之調光裝置(未圖示,例如調光窗等)中具備。於未圖示之調光裝置中,藉由電源對第1透光性導電膜1A中之透光性導電層3及第2透光性導電膜1B中之透光性導電層3施加電壓,藉此於該等之間產生電場。 而且,基於控制裝置而控制上述電場,藉此位於第1透光性導電膜1A與第2透光性導電膜1B之間之調光功能層5阻斷光,或者使光透過。 7.第1實施形態之作用效果 該透光性導電膜1由於具備無機層4,故而可穩定地保持親水性能。因此,透光性導電膜1之可靠性優異。 而且,該透光性導電膜1由於無機層4之厚度T4為上述上限以下,故而可迅速且確實地將透光性導電層3與無機層4一併蝕刻。因此,透光性導電膜1之圖案加工性優異。 又,由於形成無機層4後經過80小時以上後之無機層4之水接觸角θ1為上述上限以下,故而可藉由濕式於無機層4之表面形成均勻厚度之調光功能層5。因此,可獲得可靠性優異之調光膜20。 又,對於該透光性導電膜1而言,若無機層4係藉由濺鍍法而形成,即,若無機層4為濺鍍層,則無機層4均勻,且可具有上述厚度T4,又,耐擦傷性優異,與透光性基材2(具體而言,功能層7)之密接性變得良好。 又,對於該透光性導電膜1而言,若無機層4包含無機氧化物,則親水性尤其優異。 又,對於該透光性導電膜1而言,若第1無機氧化物層8之厚度T8及第2無機氧化物層10之厚度T10中至少1層的厚度為上述上限以下,則可迅速且確實地將透光性導電層3與無機層4一併蝕刻。 又,根據該方法,若於步驟(3)中,形成厚度T4為上述上限以下之無機層4,則於步驟(3)之後之步驟(4)中,可迅速且確實地將透光性導電層3與無機層4一併蝕刻。 又,由於形成無機層4後經過80小時以上後之無機層4之水接觸角θ1為上述上限以下,故而可藉由濕式於無機層4之表面形成均勻厚度之調光功能層5。 於該調光膜20中,由於調光功能層5與第1透光性導電膜1A所具備之無機層4、及第2透光性導電膜1B所具備之無機層4接觸,故而可具有均勻之厚度。而且,該調光膜20由於具備上述可靠性優異之透光性導電膜1,故而可靠性優異。 又,根據調光膜20之製造方法,於步驟(6)中,使無機層4與第1透光性導電膜1A之無機層4及第2透光性導電膜1B之無機層4接觸,故而可獲得具有均勻之厚度T5之調光功能層5。因此,該調光膜20之可靠性優異。 8.第1實施形態之變化例

透光性導電層3僅包含第1無機氧化物層8。 透光性導電層3之厚度T3係與第1無機氧化物層8之厚度T8相同,具體而言,例如為15 nm以上,較佳為20 nm以上,又,例如為300 nm以下,較佳為150 nm以下,更佳為50 nm以下,進而較佳為40 nm以下,尤佳為35 nm以下。 若透光性導電層3之厚度T3為上述上限以下,則於後續步驟中,可迅速且確實地將透光性導電層3與無機層4一併蝕刻。若透光性導電層3之厚度T3為上述下限以上,則即便於要求結晶質之情形時亦可確實地進行結晶化。 透光性導電層3較佳為結晶質。結晶質膜與非晶質膜相比,有親水性明確較差之情形,但本案之透光性導電膜1由於在透光性導電層3上配置親水性優異之無機層4,故而即便透光性導電層3為結晶質膜亦可較佳地使用。 透光性導電層3亦可為包含複數個無機氧化物層之積層體(參照圖4之符號13及14)之第1無機氧化物層8。較佳為第1無機氧化物層8包含組成不同之複數種(例如2種)銦錫複合氧化物(ITO)之積層體。具體而言,第1無機氧化物層8具備:第3銦錫複合氧化物層13,其係配置於透光性基材2之上表面;及第4銦錫複合氧化物層14,其係配置於第3銦錫複合氧化物層13之上表面。於第1無機氧化物層8中,配置於無機層4側之(面向無機層4)銦錫複合氧化物層(具體而言,第4銦錫複合氧化物層14)中之氧化錫含有率與構成第1無機氧化物層8之各銦錫複合氧化物層中之氧化錫含有率相比,較佳為最小,而並非最大。即,於第1無機氧化物層8中,較佳為隨著自下層向上層,氧化錫含有率變低。具體而言,於第1無機氧化物層8包含第3銦錫複合氧化物層13與第4銦錫複合氧化物層14之積層體之情形時,第4銦錫複合氧化物層14之氧化錫含有率與第3銦錫複合氧化物層13之氧化錫含有率相比較小,更具體而言,第4銦錫複合氧化物層14於第1無機氧化物層8中,具有最小之氧化錫含有率。 藉此,透光性導電層3即便於其上配置無機層4,亦可於短時間內成為結晶質ITO膜。 第4銦錫複合氧化物層14之氧化錫含有率例如為0.1質量%以上,較佳為0.5質量%以上,更佳為1質量%以上,進而較佳為3質量%以上,又,例如為8質量%以下,較佳為6質量%以下,更佳為5質量%以下。 另一方面,第4銦錫複合氧化物層14以外之層(具體而言,第3銦錫複合氧化物層13)之氧化錫含有率例如為5質量%以上,較佳為6質量%以上,更佳為9質量%以上,進而較佳為10質量%以上,又,例如為20質量%以下,較佳為15質量%以下,更佳為13質量%以下。 1-2.無機層 無機層4係配置於第1無機氧化物層8之上表面。 2.透光性導電膜之製造方法

為了使透光性導電層3結晶化,例如將經圖案化之透光性導電層3於大氣環境下,於例如80℃以上且150℃以下之溫度下,加熱(退火處理)例如30分鐘以上且90分鐘以下。 經結晶化之透光性導電層3之表面電阻例如為30 Ω/□以上,較佳為60 Ω/□以上,又,例如為200 Ω/□以下,較佳為150 Ω/□以下,更佳為100 Ω/□以下,進而較佳為90 Ω/□以下。 3.第2實施形態之作用效果 第2實施形態可發揮與第1實施形態相同之作用效果。 進而,於步驟(3)之後之步驟(5)中,更具體而言,於步驟(4)之後之步驟(5)中,使包含非晶質之第1無機氧化物層8之透光性導電層3結晶化,故而可降低透光性導電層3之表面電阻。 4.第2實施形態之變化例 於第2實施形態中,於步驟(4)之後實施步驟(5),但亦可於步驟(3)之後且步驟(4)之前實施步驟(5)。

繼而,於透光性基材2之硬塗層7'之上形成包含依序具備第1無機氧化物層8、金屬層9、第2無機氧化物層10之積層體之透光性導電層3。 第1無機氧化物層8及第2無機氧化物層10均為包含銦錫氧化物之銦錫氧化物層。具體而言,第1無機氧化物層8及第2無機氧化物層10均為藉由將包含12質量%之氧化錫與88質量%之氧化銦之燒結體之ITO靶(三井金屬礦山公司製造)於導入有成膜氣體(包含Ar及O2 (流量比Ar:O2 =100:3)之混合氣體)之真空環境下進行濺鍍而形成的厚度40 nm之銦錫導電性氧化物。 又,金屬層9包含Ag-Pd合金。具體而言,金屬層9係藉由將包含混合Ag 99質量%與Pd 1質量%而成之合金之銀合金靶於導入有成膜氣體(Ar)之真空環境下進行濺鍍而形成的厚度8 nm之銀合金層。 步驟(3):無機層之製作 繼而,於透光性導電層3之第2無機氧化物層10之上形成包含氧化矽(SiO2 )之厚度0.5 nm之無機層4。無機層4係藉由將包含純度99.99%以上之Si板之Si靶(大同特殊鋼公司製造)於導入有成膜氣體(包含Ar及O2 (流量比Ar:O2 =100:41)之混合氣體)之真空環境下進行濺鍍而形成。 藉此,製造依序具備透光性導電層3、無機層4及調光功能層5之透光性導電膜1。 實施例2~8 如表1所記載般,變更無機層4之厚度及製造方法,除此以外,以與實施例1相同之方式進行處理,製造透光性導電膜1。 比較例1 如表1所記載般,不形成無機層4,除此以外,以與實施例1相同之方式進行處理,製造透光性導電膜1。 實施例9 於步驟(2)中,將作為成膜氣體之Ar及O2 之流量比設為Ar:O2 =100:1,僅由第1無機氧化物層8製作透光性導電層3,除此以外,根據表1,以與實施例1相同之方式進行處理,製造透光性導電膜1。 再者,第1無機氧化物層8係由氧化錫含有率10質量%之第3銦錫複合氧化物層13、與氧化錫含有率3質量%之第4銦錫複合氧化物層14之積層體而形成。 實施例10 於步驟(3)中,藉由真空蒸鍍法(電子束加熱方式),由厚度0.5 nm之SiO2

再者,關於水接觸角θ1,對形成無機層4後,於25℃、相對濕度40%之環境下放置80小時之無機層4之水接觸角進行測定。 又,關於比較例1,由於不具有無機層4,故而以與上述相同之方式測定透光性導電層3之水接觸角。 再者,實施例10之透光性導電膜1雖水接觸角為50度以下,但因測定位置而水接觸角之數值有偏差,難以測定真值。 (2)厚度

cm見方之透光性導電膜1內確認到來自透光性導電層3或無機層4之殘差,且任意3處之2端子間電阻均超過60 MΩ之時間點,判斷為完成蝕刻。 蝕刻性係藉由以下之基準進行評價。 ◎:蝕刻時間未達60秒。 ○:蝕刻時間為60秒以上且為180秒以下。 △:蝕刻時間超過180秒且為300秒以下。 ×:蝕刻時間超過300秒。 (4)透光性導電層之表面電阻值 依據JIS K 7194(1994年)使用四端子法測定透光性導電層3之表面電阻值。 (5)結晶性 於140℃下對實施例9中之透光性導電層3進行加熱處理,評價透光性導電層3之結晶性。具體而言,將各例之透光性導電性膜浸漬於鹽酸(濃度:5質量%)中15分鐘後,進行水洗、乾燥,測定15 mm左右之間之端子間電阻,根據下述基準,評價結晶化速度。 ○:15 mm間之端子間電阻為10 kΩ以下。 ×:15 mm間之端子間電阻超過10 kΩ。 關於比較例1,亦以與實施例9相同之方式評價結晶化速度。 (6)收縮性 將於水100 mL中溶解氯化鈉5 mg而成之水溶液滴加於各實施例及比較例之透光性導電層3之上,或者於不存在透光性導電層3之情形時滴加於透光性基材2之上,根據下述基準,目測評價收縮性。 ○:未觀察到收縮。 △:觀察到較小之收縮,但整體而言水溶液充分地適應透光性導電層3或透光性基材2。 ×:觀察到收縮。 (7)剝離 觀察實施例1~10之無機層,如下所述般評價剝離性。 ○:未於無機層4中散見剝離部位。 △:於無機層4中散見剝離部位。 [表1]

Second Inorganic Oxide Layer The second inorganic oxide layer 10 is a conductive layer that imparts conductivity to the translucent conductive layer 3 together with the first inorganic oxide layer 8 and the metal layer 9. The second inorganic oxide layer 10 may not maintain conductivity, but preferably has conductivity. In addition, the second inorganic oxide layer 10 is also a barrier layer that prevents the metal layer 9 from being attacked by oxygen, water vapor, or sulfur oxide (SO x) that is often present in the atmosphere. The second inorganic oxide layer 10 is the uppermost layer of the light-transmitting conductive layer 3, and has a film shape (including a sheet shape), and is arranged on the entire upper surface of the metal layer 9 in contact with the upper surface of the metal layer 9 . The second inorganic oxide layer 10 contains the inorganic oxide exemplified in the first inorganic oxide layer 8. Specifically, it is an inorganic oxide that can be dissolved in the same etching solution as the etching solution used to etch the first inorganic oxide layer 8. The oxide preferably contains indium oxide, and more preferably contains ITO. That is, the second inorganic oxide layer 10 is preferably an indium-based conductive oxide layer, and more preferably an ITO layer. The content ratio of tin oxide (SnO 2 ) in indium tin composite oxide (ITO) to the total mass of indium oxide (In 2 O 3 ) and tin oxide (SnO 2 ) (SnO 2 /(SnO 2 +In 2 O 3) ) Is, for example, 6 mass% or more, preferably 8 mass% or more, more preferably 10 mass% or more, still more preferably 12 mass% or more, and, for example, 30 mass% or less, preferably 20 mass% or less, More preferably, it is 17% by mass or less. If the content ratio of tin oxide (SnO 2 ) is less than the above lower limit, the crystallinity of the second inorganic oxide layer 10 may change with time and it may become difficult to control the etching properties. If the content ratio of tin oxide (SnO 2 ) exceeds the above upper limit, the humidification reliability may be reduced. The second inorganic oxide layer 10 may be either crystalline or amorphous, for example. It is easy to follow in subsequent steps From the viewpoint of patterning, the second inorganic oxide layer 10 is preferably amorphous. From the viewpoint of obtaining a good pattern profile during etching, the first inorganic oxide layer 8 and the second inorganic oxide layer 10 are preferably all of the same film quality, more preferably all are amorphous. The thickness T10 of the second inorganic oxide layer 10 is, for example, 5 nm or more, preferably 20 nm or more, and more preferably 30 nm or more, Also, for example, it is 100 nm or less, preferably 60 nm or less, and more preferably 50 nm or less. If the thickness T10 of the second inorganic oxide layer 10 is less than the above upper limit, it can be etched quickly and surely in the subsequent steps The translucent conductive layer 3 can function as a barrier layer if the thickness T10 of the second inorganic oxide layer 10 is greater than or equal to the above lower limit. Also, the thickness T8 of the first inorganic oxide layer 8 and the second inorganic oxide layer The thickness of at least one layer in the thickness T10 of 10 is, for example, 80 nm or less, preferably 50 nm or less. Preferably, it is both the thickness T8 of the first inorganic oxide layer 8 and the thickness T10 of the second inorganic oxide layer 10 All are, for example, 50 nm or less. If the thickness T8 of the first inorganic oxide layer 8 and/or the thickness T10 of the second inorganic oxide layer 10 is less than the above upper limit, in the subsequent steps, the etching can be quickly and reliably transmitted to light性conductive layer 3. Furthermore, the thickness of the translucent conductive layer 3, that is, the total thickness of the first inorganic oxide layer 8, the metal layer 9, and the second inorganic oxide layer 10, is preferably 20 nm or more, more preferably 40 nm or more, and, for example, 230 nm or less, preferably 120 nm or less, more preferably 100 nm or less. 4. Inorganic layer The inorganic layer 4 is the uppermost layer of the light-transmitting conductive film 1, and has a film shape (including sheet The inorganic layer 4 is arranged on the entire upper surface of the second inorganic oxide layer 10 so as to be in contact with the upper surface of the second inorganic oxide layer 10. The inorganic layer 4 is opposed to the transparent conductive layer 3 (specifically, In other words, the upper surface (surface) of the second inorganic oxide layer 10) imparts a hydrophilic layer with hydrophilicity. In addition, the inorganic layer 4 will be described below, because it is preferably It is formed by a sputtering method, so it is a sputtered layer. The inorganic layer 4 contains, for example, a hydrophilic material. The hydrophilic material is not limited, and includes, for example, a hydrophilic material. Examples of the hydrophilic material include inorganic oxides such as silica, titanium oxide (specifically, TiO 2 ), and alumina (specifically, Al 2 O 3 ); for example, metal salts such as zeolite. As the hydrophilic material, an inorganic oxide is preferable, and silicon oxide is more preferable. Silicon oxide is specifically represented by SiO x , and x is, for example, 1.0 or more, preferably 1.5 or more, and, for example, 2.0 or less. Specifically, as silicon oxide, for example, SiO, SiO 2 (silicon dioxide), etc. are mentioned, preferably SiO 2 is mentioned. The thickness T4 of the inorganic layer 4 is 20 nm or less, preferably 10 nm or less, more preferably less than 10 nm, still more preferably 5.0 nm or less, particularly preferably less than 5.0 nm, most preferably 4.5 nm or less, and further It is 3.0 nm or less, and, for example, 0.01 nm or more, preferably 0.1 nm or more, more preferably 0.5 nm or more, and still more preferably 1.0 nm or more. If the thickness T4 of the inorganic layer 4 exceeds the above upper limit, the translucent conductive layer 3 cannot be etched quickly and surely. Furthermore, if the thickness T4 of the inorganic layer 4 exceeds the above upper limit, although the water contact angle θ0 of the inorganic layer 4 immediately after the formation of the inorganic layer 4 described below can be set to be low, the ratio of the following water contact angle (θ1/ θ0) becomes higher (specifically, 4.0 or more). Therefore, the water contact angle θ1 of the inorganic layer 4 becomes higher after 80 hours or more after the formation of the inorganic layer 4. Therefore, the water contact angle θ1 of the inorganic layer 4 may vary after 80 hours or more after the formation of the inorganic layer 4. On the other hand, if the thickness T4 of the inorganic layer 4 is more than the above lower limit, excellent wettability can be obtained. In addition, the ratio of the thickness T4 of the inorganic layer 4 to the thickness T10 of the second inorganic oxide layer 10 (thickness T4 of the inorganic layer 4/thickness T10 of the second inorganic oxide layer 10) is, for example, 0.01 or more, preferably 0.02 Above, for example, it is 0.50 or less, preferably 0.25 or less, more preferably 0.15 or less, and still more preferably 0.10 or less. If the ratio of the above thickness is not less than the above lower limit, excellent wettability can be obtained. If the ratio of the above-mentioned thickness exceeds the above-mentioned upper limit, the translucent conductive layer 3 cannot be etched quickly and surely. If the ratio of the above-mentioned thickness exceeds the above-mentioned lower limit, the water contact angle θ1 of the inorganic layer 4 may vary after 80 hours or more after the formation of the inorganic layer 4. Moreover, the water contact angle θ1 of the inorganic layer 4 (described below, the water contact angle θ1 after 80 hours or more after the formation of the inorganic layer 4) is 50 degrees or less, preferably 40 degrees or less, more preferably 30 degrees or less, It is more preferably 20 degrees or less, more preferably less than 20 degrees, most preferably 10 degrees or less, and, for example, 0 degrees or more, preferably 1 degree or more, and more preferably 5 degrees or more. The water contact angle θ1 of the inorganic layer 4 is based on the formation of the inorganic layer 4, according to JIS R1753:2013 for normal temperature (specifically, 20-40°C) and normal humidity (specifically, relative humidity of 30% or more and 70% or less) The inorganic layer 4 was placed in the environment for more than 80 hours for measurement. A more specific method for measuring the water contact angle θ1 is described in the subsequent examples. If the water contact angle θ1 of the inorganic layer 4 after more than 80 hours after the formation of the inorganic layer 4 exceeds the above upper limit, it is impossible to form a light-adjusting functional layer 5 of uniform thickness on the surface of the inorganic layer 4 by wet method (described below) . 5. Manufacturing method of translucent conductive film Next, the method of manufacturing the translucent conductive film 1 is demonstrated. The method includes: step (1), which prepares a translucent substrate 2; step (2), which is to form a translucent conductive layer 3 on the surface of the translucent substrate 2; and step (3), which The inorganic layer 4 is formed on the surface of the translucent conductive layer 3. Hereinafter, each step is described in detail. 5-1. Step (1) In step (1), the base substrate 6 is first prepared. Then, the functional layer 7 is arranged on the upper surface of the base substrate 6. For example, the functional layer 7 is configured by a wet type. Specifically, first, the resin composition is applied to the upper surface of the base substrate 6. After that, when the resin composition contains an active energy ray curable resin, the active energy ray is irradiated. Thereby, a functional layer 7 in a film shape is formed on the entire upper surface of the translucent base 2. That is, the translucent substrate 2 provided with the base substrate 6 and the functional layer 7 is produced. 5-2. Step (2) In step (2), after step (1), the translucent conductive layer 3 is disposed (laminated) on the upper surface of the functional layer 7 by, for example, dry type. Specifically, each of the first inorganic oxide layer 8, the metal layer 9, and the second inorganic oxide layer 10 is sequentially arranged by a dry method. Examples of the dry method include a vacuum vapor deposition method, a sputtering method, an ion plating method, and the like. Preferably, the sputtering method can be cited. Examples of the gas used in the sputtering method include inert gases such as Ar. In addition, a reactive gas such as oxygen may be used in combination as necessary. When a reactive gas is used in combination, the ratio of the flow rate of the reactive gas to the flow rate of the inert gas (the flow rate of the reactive gas/the flow rate of the inert gas) is, for example, 0.1/100 or more, preferably 0.5/100 or more, and , For example, 10/100 or less, preferably 5/100 or less. Specifically, in the formation of each of the first inorganic oxide layer 8 and the second inorganic oxide layer 10, it is preferable to use an inert gas and a reactive gas together as a gas. On the other hand, in the formation of the metal layer 9, it is preferable to use an inert gas alone as the gas. In the formation of the second inorganic oxide layer 10, it is preferable to use an inert gas and a reactive gas together as a gas. It is preferable to form the translucent conductive layer 3 in an amorphous form. Specifically, an amorphous first inorganic oxide layer 8 and an amorphous second inorganic oxide layer 10 are formed. As a result, the transparent conductive layer 3 in which the first inorganic oxide layer 8, the metal layer 9, and the second inorganic oxide layer 10 are sequentially formed on the transparent substrate 2 is formed. The surface resistance of the transparent conductive layer 3 (specifically, the surface resistance of the amorphous transparent conductive layer 3) is, for example, 1 Ω/□ or more, preferably 3 Ω/□ or more, more preferably 8 Ω /□ or more, for example, 100 Ω/□ or less, preferably 50 Ω/□ or less, and more preferably 30 Ω/□ or less. 5-3. Step (3) In step (3), after step (2), the inorganic layer 4 is arranged (laminated) on the upper surface of the second inorganic oxide layer 10, for example, by dry method. Examples of the dry method include a vacuum vapor deposition method, a sputtering method, an ion plating method, and the like. From the viewpoint of uniformly forming the inorganic layer 4 with the above-mentioned thickness T4, a sputtering method is preferable. On the other hand, if it is a vacuum evaporation method, the deviation of the thickness T4 of the inorganic layer 4 may increase, and the wettability of the inorganic layer 4 may decrease. Furthermore, the inorganic layer 4 is self-transmitting from the light-transmitting conductive layer 3. The case of peeling. Examples of the gas used in the sputtering method include inert gases such as Ar. In addition, a reactive gas such as oxygen may be used in combination as necessary. When a reactive gas is used in combination, the ratio of the flow rate of the reactive gas to the flow rate of the inert gas (the flow rate of the reactive gas/the flow rate of the inert gas) is, for example, 1/100 or more, preferably 10/100 or more, more It is preferably 20/100 or more, and, for example, 90/100 or less, and more preferably 50/100 or less. Immediately after the formation of the inorganic layer 4 (specifically, within 500 minutes after the formation of the inorganic layer 4), the water contact angle θ0 of the inorganic layer 4 is 50 degrees or less, preferably 40 degrees or less, more preferably 20 degrees or less, and more It is preferably 10 degrees or less, and, for example, 0 degrees or more, preferably 5 degrees or more, more preferably more than 6 degrees, and even more preferably 7 degrees or more. On the other hand, the water contact angle θ1 of the inorganic layer 4 after 80 hours or more has passed after the formation of the inorganic layer 4 changes with respect to the water contact angle θ0 immediately after the formation of the inorganic layer 4. Specifically, the ratio (θ1/θ0) of the water contact angle θ1 after 80 hours or more after the formation of the inorganic layer 4 to the water contact angle θ0 immediately after the formation of the inorganic layer 4 is, for example, 0.3 or more, preferably 0.5 or more. It is more preferably 1.0 or more, still more preferably 2.0 or more, and, for example, less than 4.5, preferably 4.0 or less, more preferably 3.5 or less, still more preferably 3.0 or less, and particularly preferably less than 3.0. If the above ratio is equal to or less than the above upper limit, it is possible to suppress variation in the water contact angle θ1 of the inorganic layer 4 after 80 hours or more have passed after the formation of the inorganic layer 4. Thereby, the light-transmitting conductive film 1 provided with the light-transmitting base material 2, the light-transmitting conductive layer 3, and the inorganic layer 4 in this order is obtained. The total thickness of the translucent conductive film 1 is, for example, 2 μm or more, preferably 20 μm or more, and for example, 300 μm or less, preferably 200 μm or less, and more preferably 150 μm or less. The light-transmitting conductive film 1 is an industrially available device. 5-4. Step (4) The manufacturing method of the light-transmitting conductive film 1 further includes the step (4) of etching the light-transmitting conductive layer 3 after the step (3). In step (4), after step (3), the transparent conductive layer 3 is etched. Specifically, the transparent conductive layer 3 and the inorganic layer 4 are etched together, and the transparent conductive layer 3 and the inorganic layer 4 are patterned into a specific shape. The etching solution is not particularly limited as long as it is a solution that can dissolve the light-transmitting conductive layer 3, and examples thereof include nitric acid, phosphoric acid, acetic acid, hydrochloric acid, sulfuric acid, oxalic acid, and mixtures of these. The etching time is, for example, 5 minutes or less, preferably 4 minutes or less, more preferably 3 minutes or less, and, for example, 0.05 minutes or more, preferably 0.1 minutes or more, and more preferably 0.5 minutes or more. If the etching time is less than or equal to the above upper limit, the manufacturing method of the light-transmitting conductive film 1 can be implemented by a roll-to-roll method with excellent production efficiency. Thereby, a light-transmitting conductive film 1 including a light-transmitting base material 2, a patterned light-transmitting conductive layer 3, and a patterned inorganic layer 4 in this order is obtained. Furthermore, the above-mentioned manufacturing method is implemented by a roll-to-roll method. In addition, part or all of them may be implemented in batches. 6. Manufacturing method of light control film Next, the method of manufacturing the light control film 20 using the said translucent conductive film 1 is demonstrated with reference to FIG. 2. FIG. The method is shown in FIG. 2 and includes: step (6), which is to manufacture two light-transmitting conductive films 1; and step (7), which is to sandwich the dimming by two light-transmitting conductive films 1 Functional layer 5. 6-1. Step (6) In step (6), two light-transmitting conductive films 1 described above are produced. Furthermore, one light-transmitting conductive film 1 may be cut and processed to prepare two light-transmitting conductive films 1. The two translucent conductive films 1 are the first translucent conductive film 1A and the second translucent conductive film 1B. 6-2. Step (7) Step (7) is implemented after step (6). In step (7), on the upper surface (surface) of the inorganic layer 4 in the first translucent conductive film 1A, the dimming function layer 5 is formed, for example, by a wet method. The dimming function layer 5 is, for example, an electrochromic layer or a liquid crystal layer, and preferably a liquid crystal layer. In this step (7), for example, a solution containing a liquid crystal composition is applied to the upper surface of the inorganic layer 4 in the first translucent conductive film 1A. Examples of the liquid crystal composition include known ones contained in the solution, for example, the liquid crystal dispersion resin described in Japanese Patent Application Laid-Open No. 8-194209. Then, the second transparent conductive film 1B is laminated on the surface of the coating film so that the inorganic layer 4 of the second transparent conductive film 1B is in contact with the surface of the coating film. Thereby, the coating film is sandwiched by the two light-transmitting conductive films 1, that is, the first light-transmitting conductive film 1A and the second light-transmitting conductive film 1B. After that, the coating film is appropriately treated (in the case where the liquid crystal composition contains an ultraviolet curable composition, ultraviolet light is irradiated) to form the dimming function layer 5. The light control function layer 5 is formed between the inorganic layer 4 of the first light-transmitting conductive film 1A and the inorganic layer 4 of the second light-transmitting conductive film 1B. Thereby, the light control film 20 provided with the 1st translucent conductive film 1A, the light control function layer 5, and the 2nd translucent conductive film 1B in this order is obtained. In addition, the light control film 20 is provided in a light control device (not shown, for example, a light control window, etc.) equipped with a power supply (not shown), a control device (not shown), and the like. In a dimming device not shown, a voltage is applied to the light-transmitting conductive layer 3 in the first light-transmitting conductive film 1A and the light-transmitting conductive layer 3 in the second light-transmitting conductive film 1B by a power supply, This generates an electric field between them. Furthermore, by controlling the above-mentioned electric field by the control device, the dimming function layer 5 located between the first translucent conductive film 1A and the second translucent conductive film 1B blocks light or transmits light. 7. Effects of the first embodiment Since the light-transmitting conductive film 1 includes the inorganic layer 4, the hydrophilic performance can be stably maintained. Therefore, the reliability of the translucent conductive film 1 is excellent. Furthermore, since the thickness T4 of the inorganic layer 4 of the transparent conductive film 1 is equal to or less than the above upper limit, the transparent conductive layer 3 and the inorganic layer 4 can be etched together quickly and reliably. Therefore, the pattern processability of the translucent conductive film 1 is excellent. In addition, since the water contact angle θ1 of the inorganic layer 4 after more than 80 hours after the formation of the inorganic layer 4 is below the above upper limit, the light control function layer 5 with a uniform thickness can be formed on the surface of the inorganic layer 4 by a wet method. Therefore, the light control film 20 excellent in reliability can be obtained. Furthermore, for the translucent conductive film 1, if the inorganic layer 4 is formed by a sputtering method, that is, if the inorganic layer 4 is a sputtering layer, the inorganic layer 4 is uniform and may have the above-mentioned thickness T4, and , The scratch resistance is excellent, and the adhesion with the translucent base material 2 (specifically, the functional layer 7) becomes good. In addition, in this light-transmitting conductive film 1, if the inorganic layer 4 contains an inorganic oxide, the hydrophilicity is particularly excellent. In addition, for the translucent conductive film 1, if the thickness of at least one of the thickness T8 of the first inorganic oxide layer 8 and the thickness T10 of the second inorganic oxide layer 10 is less than the above upper limit, it can be quickly and The transparent conductive layer 3 and the inorganic layer 4 are surely etched together. Furthermore, according to this method, if the inorganic layer 4 having a thickness T4 below the upper limit is formed in step (3), then in step (4) subsequent to step (3), the light-transmitting conductive layer can be quickly and surely The layer 3 and the inorganic layer 4 are etched together. In addition, since the water contact angle θ1 of the inorganic layer 4 after more than 80 hours after the formation of the inorganic layer 4 is below the above upper limit, the light control function layer 5 with a uniform thickness can be formed on the surface of the inorganic layer 4 by a wet method. In the light control film 20, since the light control function layer 5 is in contact with the inorganic layer 4 provided in the first light-transmitting conductive film 1A and the inorganic layer 4 provided in the second light-transmitting conductive film 1B, it can have Uniform thickness. Furthermore, since this light control film 20 is equipped with the above-mentioned translucent conductive film 1 which is excellent in reliability, it is excellent in reliability. In addition, according to the method of manufacturing the light control film 20, in step (6), the inorganic layer 4 is brought into contact with the inorganic layer 4 of the first light-transmitting conductive film 1A and the inorganic layer 4 of the second light-transmitting conductive film 1B, Therefore, the dimming function layer 5 with a uniform thickness T5 can be obtained. Therefore, the reliability of the dimming film 20 is excellent. 8. Modifications of the first embodiment.

It is preferably 20 Ω/□ or less, and more preferably 15 Ω/□ or less. In addition, in the first embodiment, the functional layer 7 is provided in the translucent substrate 2. However, for example, as shown in FIG. 3, the functional layer 7 may not be provided, and only the base substrate 6 constitutes the translucent substrate. 2. That is, as shown in FIG. 3, in this case, the translucent substrate 2 does not include the functional layer 7 and only includes the base substrate 6. The light-transmitting conductive layer 3 (specifically, the first inorganic oxide layer 8) is arranged so as to be in contact with the upper surface of the base substrate 6 (the light-transmitting substrate 2).

Specifically, the first inorganic oxide layer 8 is disposed on the entire upper surface of the base substrate 6. In addition, as shown in FIG. 2, the two light-transmitting conductive films 1, that is, the first light-transmitting conductive film 1A and the second light-transmitting conductive film 1B are each provided with a specific inorganic layer 4, but for example, although not shown As shown, specifically, only the first light-transmitting conductive film 1A may include the inorganic layer 4, and the second light-transmitting conductive film 1B may not include the inorganic layer 4 to form the second light-transmitting conductive film 1B. In this modified example, although not shown, the second light-transmitting conductive film 1B includes a light-transmitting base material 2 and a light-transmitting conductive layer 3 in this order. Moreover, as shown in FIG. 1, in the translucent conductive film 1 of the first embodiment, the translucent conductive layer 3 includes a first inorganic oxide layer 8, a metal layer 9, and a second inorganic oxide layer 10 in this order. . However, although not shown in the figure, for example, a second metal layer and a third inorganic oxide layer may be sequentially arranged on the second inorganic oxide layer 10.

In the second translucent conductive film 1B, the surface of the translucent conductive layer 3, specifically, the surface of the second inorganic oxide layer 10 is exposed. The second inorganic oxide layer 10 of the second translucent conductive film 1B is in direct contact with the light control function layer 5. Furthermore, in the first embodiment, as shown in FIG. 1, the functional layer 7 is arranged on the upper surface of the base substrate 6. Although not shown, the functional layer 7 may be arranged on the base substrate 6. Both the surface and the bottom surface. According to each of the above-mentioned modification examples, the same effects as those of the first embodiment can be exerted. <Second Embodiment> In the second embodiment, the same reference numerals are given to the same members and steps as in the first embodiment, and detailed descriptions thereof are omitted. 1. Light-transmitting conductive film The light-transmitting conductive layer 3, as shown in FIG. 1, is provided with three layers of a first inorganic oxide layer 8, a metal layer 9, and a second inorganic oxide layer 10, but as shown in FIG. 4, In the second embodiment, only one layer of the first inorganic oxide layer 8 is provided. As shown in FIG. 4, the light-transmitting conductive layer 3 does not include the metal layer 9. Therefore, from the viewpoint of obtaining a low specific resistance, it is preferably crystalline. 1-1. Translucent conductive layer The translucent conductive layer 3 contains only the first inorganic oxide layer 8. The thickness T3 of the translucent conductive layer 3 is the same as the thickness T8 of the first inorganic oxide layer 8.

If the thickness T3 of the light-transmitting conductive layer 3 is less than or equal to the above upper limit, the light-transmitting conductive layer 3 and the inorganic layer 4 can be etched quickly and surely in the subsequent step. If the thickness T3 of the translucent conductive layer 3 is greater than or equal to the above lower limit, crystallization can be performed reliably even when crystallinity is required. The translucent conductive layer 3 is preferably crystalline. The crystalline film has a clearly inferior hydrophilicity compared with the amorphous film. However, the transparent conductive film 1 in this case is provided with an inorganic layer 4 with excellent hydrophilicity on the transparent conductive layer 3, so even if it transmits light The conductive layer 3 is a crystalline film and can also be preferably used. The translucent conductive layer 3 may also be the first inorganic oxide layer 8 of a laminate (refer to symbols 13 and 14 in FIG. 4) including a plurality of inorganic oxide layers.

That is, in the first inorganic oxide layer 8, it is preferable that the tin oxide content becomes lower as it moves from the lower layer to the upper layer. Specifically, when the first inorganic oxide layer 8 includes a laminate of the third indium tin composite oxide layer 13 and the fourth indium tin composite oxide layer 14, the oxidation of the fourth indium tin composite oxide layer 14 The tin content is smaller than the tin oxide content of the third indium tin composite oxide layer 13. More specifically, the fourth indium tin composite oxide layer 14 has the smallest oxidation in the first inorganic oxide layer 8. Tin content rate.

Furthermore, in the step (5) after the step (3), more specifically, in the step (5) after the step (4), the first inorganic oxide layer 8 containing amorphous is made transparent The conductive layer 3 is crystallized, so the surface resistance of the transparent conductive layer 3 can be reduced. 4. Modifications of the second embodiment In the second embodiment, step (5) is implemented after step (4), but step (5) may be implemented after step (3) and before step (4).

That is, as shown in FIG. 6, in this case, the translucent substrate 2 does not include the functional layer 7 and only includes the base substrate 6. The light-transmitting conductive layer 3 (specifically, the first inorganic oxide layer 8) is arranged so as to be in contact with the upper surface of the base substrate 6 (the light-transmitting substrate 2). With these modified examples, the same functions and effects as in the second embodiment can also be exerted. In addition, it is also possible to appropriately combine the first embodiment, the second embodiment, and these modified examples described above. [Examples] Hereinafter, the present invention will be described in detail using examples, but the present invention is not limited to the examples as long as it does not exceed the gist of the invention, and various changes and modifications can be made based on the technical idea of the present invention. Examples and comparative examples are shown below to explain the present invention more specifically. In addition, the present invention is not limited to Examples and Comparative Examples at all. In addition, specific numerical values such as the blending ratio (content ratio), physical property values, and parameters used in the following description can be replaced with the blending ratios (content ratio), physical property values, etc. corresponding to those described in the above-mentioned "embodiment". The upper limit (defined as the value of "below" or "not reached") or the lower limit (defined as the value of "above" or "exceeding") corresponding to the record. Example 1 Step (1): Fabrication of a light-transmitting substrate Prepare a base substrate 6 containing a polyethylene terephthalate (PET) film (manufactured by Mitsubishi Resin) with a thickness of 50 μm, and then apply it to the base substrate The surface of 6 (the main surface on the side where the light-transmitting conductive layer 3 is formed) is coated with an ultraviolet curable resin containing acrylic resin, and cured by ultraviolet irradiation to form a hard coat layer 7'with a thickness of 2 μm. Thereby, the translucent substrate 2 having the base substrate 6 and the hard coat layer 7'in this order is produced. Step (2): Fabrication of the light-transmitting conductive layer. Then, the hard coat layer 7'of the light-transmitting substrate 2 is formed with a first inorganic oxide layer 8, a metal layer 9, and a second inorganic oxide layer in this order. The transparent conductive layer 3 of the laminated body of the material layer 10. Both the first inorganic oxide layer 8 and the second inorganic oxide layer 10 are indium tin oxide layers containing indium tin oxide. Specifically, the first inorganic oxide layer 8 and the second inorganic oxide layer 10 are both ITO targets (manufactured by Mitsui Metal Mining Co., Ltd.) by sintering 12% by mass of tin oxide and 88% by mass of indium oxide. ) A conductive oxide of indium tin with a thickness of 40 nm is formed by sputtering in a vacuum environment into which a film forming gas (a mixed gas containing Ar and O 2 (flow ratio Ar:O 2 =100:3)) is introduced. In addition, the metal layer 9 contains an Ag-Pd alloy. Specifically, the thickness of the metal layer 9 is formed by sputtering a silver alloy target containing an alloy of 99% by mass of Ag and 1% by mass of Pd in a vacuum environment in which a film-forming gas (Ar) is introduced. 8 nm silver alloy layer. Step (3): Fabrication of the inorganic layer Next, an inorganic layer 4 containing silicon oxide (SiO 2 ) with a thickness of 0.5 nm is formed on the second inorganic oxide layer 10 of the translucent conductive layer 3. The inorganic layer 4 is formed by introducing a Si target (manufactured by Datong Special Steel Co., Ltd.) containing a Si plate with a purity of 99.99% or more into a film-forming gas (including Ar and O 2 (flow ratio Ar: O 2 = 100: 41)) It is formed by sputtering in a vacuum environment of mixed gas). Thereby, the light-transmitting conductive film 1 including the light-transmitting conductive layer 3, the inorganic layer 4, and the light-adjusting function layer 5 in this order is manufactured. Examples 2 to 8 As described in Table 1, except for changing the thickness and manufacturing method of the inorganic layer 4, the treatment was carried out in the same manner as in Example 1, and the translucent conductive film 1 was manufactured. Comparative Example 1 As described in Table 1, except that the inorganic layer 4 was not formed, the treatment was performed in the same manner as in Example 1 to produce a translucent conductive film 1. Example 9 In step (2), the flow ratio of Ar and O 2 as the film forming gas was set to Ar:O 2 =100:1, and the light-transmitting conductive layer 3 was made from only the first inorganic oxide layer 8 Except for this, according to Table 1, the treatment was performed in the same manner as in Example 1 to produce a translucent conductive film 1. Furthermore, the first inorganic oxide layer 8 is a laminate of a third indium tin composite oxide layer 13 with a tin oxide content of 10% by mass, and a fourth indium tin composite oxide layer 14 with a tin oxide content of 3% by mass. Body and formed. Example 10 In step (3), the inorganic layer 4 was formed from a SiO 2 layer with a thickness of 0.5 nm by a vacuum evaporation method (electron beam heating method), except that the treatment was performed in the same manner as in Example 1 , Manufacturing a translucent conductive film 1. Evaluation The following items were evaluated, and the results are shown in Table 1. (1) Water contact angle The water contact angle (θ0, θ1) of the inorganic layer 4 of Examples 1-10 is that a water droplet with a diameter of 1.5 mm is formed at the tip of the needle, which is brought into contact with the surface of the inorganic layer 4, and the water droplet is moved to the inorganic layer Above 4, the static contact angle between the water drop and the inorganic layer 4 was measured by a contact angle meter (made by Kyowa Interface Science Co., Ltd., CA-X type). The measurement was performed at 5 places, and when the difference between the maximum angle and the minimum angle was 5.0 degrees or less, it was judged that the measurement could be accurately performed, and the simple average value of the water contact angle was used to judge the wettability. When the water contact angle exceeds 5.0 degrees, accurate measurement cannot be performed, and it is assumed that the dimming function layer 5 partially shrinks, so regardless of the value, the wettability is regarded as "low". Furthermore, with regard to the water contact angle θ1, the water contact angle of the inorganic layer 4 was measured after the inorganic layer 4 was formed, and placed in an environment of 25° C. and a relative humidity of 40% for 80 hours. In addition, in Comparative Example 1, since the inorganic layer 4 was not provided, the water contact angle of the translucent conductive layer 3 was measured in the same manner as described above. Furthermore, although the light-transmitting conductive film 1 of Example 10 has a water contact angle of 50 degrees or less, the numerical value of the water contact angle varies depending on the measurement position, and it is difficult to measure the true value. (2) Thickness The thickness of the base substrate 6 was measured using a film thickness meter (manufactured by Ozaki Manufacturing Co., Ltd. (Peacock (registered trademark)), device name "digital dial gauge DG-205"). Measure the hard coat layer 7, the first inorganic oxide layer 8, the metal layer 9, and the second inorganic oxide layer 10 by cross-sectional observation using a transmission electron microscope (manufactured by Hitachi, Ltd., device name "HF-2000") The thickness. The thickness of the inorganic layer 4 was measured using a fluorescent X-ray analyzer (manufactured by Rigaku, device name "ZSX Primus II") (the thickness of the inorganic layer was obtained by subtracting the SiKa intensity from the translucent substrate). Furthermore, when performing fluorescent X-ray analysis, prepare in advance as follows. That is, a sample with a silicon oxide (SiO 2 ) layer with target thicknesses of 100 nm, 150 nm, and 200 nm formed on a PET substrate with a thickness of 50 μm is produced, and the fluorescent X-ray analyzer measures the amount of each sample. The SiKa intensity (the value obtained by subtracting the SiKa intensity from the PET substrate), and the actual film thickness of the silicon oxide layer of each sample was obtained by a transmission electron microscope. Based on the obtained SiKa intensity value and the actual film thickness, a calibration curve is prepared, and the thickness of the inorganic layer 4 is obtained based on the SiKa intensity. (3) Etching time and etching properties: 20 pieces of light-transmitting conductive film 1 cut into 5 cm squares were made, and immersed in an etching solution heated to 40°C (manufactured by ADEKA, product name "Adeka Chelumica SET-500"")in. After that, one sheet was taken out every 15 seconds for the immersion time, washed with water, wiped with water (to dry), confirmed the appearance of the translucent conductive film 1, and measured the resistance between two terminals at any three locations. In addition, the resistance measurement between the two terminals was carried out with a tester, and the distance between the terminals was set to 1.5 cm when the measurement was performed. Moreover, in the evaluation of the etching time, the residual error from the transparent conductive layer 3 or the inorganic layer 4 cannot be confirmed visually in the 5 cm square transparent conductive film 1, and the resistance between 2 terminals at any 3 locations When it exceeds 60 MΩ, it is judged that the etching is completed. The etching properties were evaluated based on the following criteria. ◎: The etching time is less than 60 seconds. ○: The etching time is 60 seconds or more and 180 seconds or less. △: The etching time exceeds 180 seconds and is 300 seconds or less. ×: The etching time exceeds 300 seconds. (4) The surface resistance of the light-transmitting conductive layer was measured according to JIS K 7194 (1994) using the four-terminal method. (5) Crystallinity The translucent conductive layer 3 in Example 9 was heated at 140° C. to evaluate the crystallinity of the translucent conductive layer 3. Specifically, the light-transmitting conductive film of each example was immersed in hydrochloric acid (concentration: 5 mass%) for 15 minutes, washed with water and dried, and the resistance between the terminals was measured between about 15 mm. According to the following criteria, Evaluate the crystallization rate. ○: The resistance between terminals between 15 mm is 10 kΩ or less. ×: The resistance between terminals between 15 mm exceeds 10 kΩ. Regarding Comparative Example 1, the crystallization rate was also evaluated in the same manner as in Example 9. (6) Shrinkage: Drop an aqueous solution of 5 mg of sodium chloride in 100 mL of water onto the translucent conductive layer 3 of each of the examples and comparative examples, or if there is no translucent conductive layer 3 In this case, it was dropped on the translucent base material 2, and the shrinkage was visually evaluated based on the following criteria. ○: No shrinkage is observed. △: Small shrinkage is observed, but the aqueous solution adequately adapts to the light-transmitting conductive layer 3 or the light-transmitting base material 2 as a whole. ×: Shrinkage is observed. (7) Peeling The inorganic layers of Examples 1 to 10 were observed, and peeling properties were evaluated as follows. ○: No peeling sites are scattered in the inorganic layer 4. △: Peeling sites are scattered in the inorganic layer 4.
