- the low-frequency electromagnetic shielding member 15 the same conductive mesh member as that in Example 1 was used.
- the insulating plate 11 provided with the high-frequency electromagnetic shielding member 13 and the low-frequency electromagnetic shielding member 15 was disposed with a spacer 40 interposed therebetween. As a result, an air layer 50 having a thickness of 6 mm was formed between the insulating plates 11.

- it is the same as that of Example 1 mentioned above.
- a conductive film (high-frequency electromagnetic shielding member 17) using an indium tin oxide film (conductive thin film 18) was attached to an insulating plate (glass plate) 11. Further, the conductive film (high-frequency electromagnetic shielding member 17) is positioned on the outermost side so that the conductive film (high-frequency electromagnetic shielding member 17), 3 mm glass plate (insulating plate 11), adhesive layer 16, conductive mesh member ( Low frequency electromagnetic shielding member 15), 6 mm glass plate (sandwiched insulator 22), conductive mesh member (low frequency electromagnetic shielding member 15), adhesive layer 16, 3 mm glass plate (insulating plate 11), conductive film (high frequency The electromagnetic shielding members 17) were laminated in this order.
- the conductive film (high frequency electromagnetic shielding member 17) is about 20 mm from the edge 11-3 of the glass plate (insulator 11), and the conductive mesh member (low frequency electromagnetic shielding member 15) is the edge of the glass plate (insulating plate 11).
- the film was stretched about 11 to 15 mm. After integrating them all, the protruding conductive film (high-frequency electromagnetic shielding member 17) is bent outward, and the protruding conductive mesh member (low-frequency electromagnetic shielding member 15) is further bent outward to form the conductive film (high-frequency electromagnetic wave). After being connected to the conductive thin film 18 of the electromagnetic shielding member 17), the entire edge portion thereof was covered with a copper tape (conductive member 30 for edge connection). At this time, as shown in FIG.

- the indium tin oxide film (conductive thin film 18) was also in direct contact and conducted.
- the measured values of the electromagnetic shielding effects of the electromagnetic shielding panels 100, 100a, 100b, and 100e of Examples 1 to 3 and the comparative example are measured by the measurement system shown in FIG. 10, and are referenced by the measurement system shown in FIG. The value was measured.
- the electromagnetic shielding panels 100, 100a, 100b, and 100e manufactured in Examples 1 to 3 and the comparative example were fitted into the window frame 120 as shown in FIG.

Measurements were made to obtain actual measurement values. Further, as shown in FIG. 11, the transmission antenna 500 and the reception antenna 600 are opposed to each other in free space, and the electric field strength is similarly measured to obtain a reference value. Furthermore, the attenuation value was calculated by subtracting the actual measurement value from the reference value, and the measurement result was obtained. About the detail of the measurement, it carried out based on the Defense Agency standard NDS C0012 of an electromagnetic shielding room test method. The measurement results are shown in Table 1 below.
- the thickness dimension as the window member is almost the same, the material of the conductive mesh member (low frequency electromagnetic shielding member 15) used is the same, and the low frequency electromagnetic shielding member 15 is also the same.
- the number of high-frequency electromagnetic shielding members 13 is also the same. However, there are significant differences in electromagnetic shielding performance. This is because, in the comparative example, the low-frequency electromagnetic shielding member 15 and the high-frequency electromagnetic shielding member 13 are overlapped, but in Example 1, they are arranged apart from each other.
- Example 2 and Example 3 when the measurement results of Example 1, Example 2 and Example 3 are compared, it is understood that the electromagnetic shielding performance is improved as the number of layers involved in the shielding property of electromagnetic waves increases. For example, when the measurement results of Example 1 and Example 2 are compared, there is no significant difference between the two in terms of electromagnetic shielding performance in the low frequency region, but Example 2 is different from Example 1 in the high frequency region. It is understood that it has high electromagnetic shielding performance in comparison. Furthermore, in Example 3, since the surface resistance value is low, it is understood that the electromagnetic shielding performance is higher in the higher frequency region than in Example 2.

図1に示されるように、本発明の第1の実施の形態による電磁遮蔽パネル100は、1対の遮蔽板10と、遮蔽板10間に挟持された被挟持体20と、エッジ接続用導電部材30とを備えている。
図3を参照すると、本発明の第2の実施の形態による電磁遮蔽パネル100aは、被挟持体20aの構成を除き、上述した第1の実施の形態による電磁遮蔽パネル100と同様である。従って、以下においては、差異のみについて説明することとする。
図4を参照すると、本発明の第3の実施の形態による電磁遮蔽パネル100bは、遮蔽板10b、特に、高周波電磁遮蔽部材17の構成を除き、上述した第1の実施の形態による電磁遮蔽パネル100と同様である。従って、以下においては、差異たる高周波電磁遮蔽部材17について説明する。
図5を参照すると、本発明の第4の実施の形態による窓部材200cは、上述した第1の実施の形態による電磁遮蔽パネル100を窓枠120に取り付ける構造に対して、更にエッジ接続用導電部材30と窓枠120との間の接触圧を調整するための圧調整機構130を配してなるものである。圧調整機構130は、金属板132と金属製の調整ネジ134とを備えている。調整ネジ134を押し込むことによって金属板132が電磁遮蔽パネル100に向かって押し付けられることから、たとえ窓枠120等の部品のサイズのばらつき等により部品間に多少のギャップが生じてしまったとしても、窓枠120に設けられたシールドガスケット110とエッジ接続用導電部材30との間の接触圧の調整を適切に図ることができる。また、かかる構成の圧調整機構130を用いると、電磁波の漏洩の生じさせるような開口を設けることなく、接触圧の調整を行うことができる。なお、調整ネジ134としては、例えば、すりわり付き止めねじ(Setscrew)を用いることができる。
上述した第1の実施の形態による窓部材200は、扉や壁などに対して嵌め込む形式の窓部材であったが、図6を参照すると、本発明の第5の実施の形態による窓部材200dは、引き窓形式の窓部材である。詳しくは、本実施の形態による窓部材200dは、上述した第1の実施の形態による電磁遮蔽パネル100に対して、更に導電枠140を取り付けてなる構成を備えている。
図7を参照すると、本発明による第6の実施の形態は、計測等に使用する閉空間310を有するシールドルーム300に対して、上述した第1の実施の形態による電磁遮蔽パネル100を用いた窓部材200を適用してなるものである。上述した窓部材200を用いれば、電磁遮蔽パネル100と、電磁遮蔽パネル100の縁辺部および窓枠120などからの電磁波の漏洩を抑え、計測等に使用されるような非常に厳しい遮蔽性能要求に対しても応えることができる。従って、本実施の形態によるシールドルーム300においては、電磁遮蔽効果を損なうことなく、比較的大きな窓部を設けることが可能となる。
図8を参照すると、本発明による第7の実施の形態は、計測等に使用する閉空間410を有するシールドボックス400に対して、上述した第1の実施の形態による電磁遮蔽パネル100を用いた窓部材200を適用してなるものである。本発明によれば、第6の実施の形態の場合と同様に、厳しい遮蔽性能要求をクリアしつつ、シールドボックス400に対して視認性を付与することができる。
実施例1では、第1の実施の形態による電磁遮蔽パネル100において、高周波電磁遮蔽部材13として酸化錫膜を用い、また、エッジ接続用導電部材30として銅テープを用いた。
比較例として、図9に示されるような構成の電磁遮蔽パネル100eを作製した。詳しくは、2枚の絶縁板11の夫々として厚さ3mmのガラスを用いた。絶縁体11の第1主面11-1は、端部を除き、何にも覆われていない状態とし、絶縁体11の第2主面11-2は、高周波電磁遮蔽部材13と低周波電磁遮蔽部材15とで覆われている。詳しくは、第2主面11-2上に高周波電磁遮蔽部材13が形成されており、その上に、低周波電磁遮蔽部材15が形成されている。低周波電磁遮蔽部材15は、第1の実施の形態と同様にエッジ11-3を覆い且つ第1主面11-1のエッジ11-3近辺をも覆っている。ここで、高周波電磁遮蔽部材13としては、遮蔽ガラスに一般的に用いられていた銀膜を用いた。銀膜の表面抵抗は20Ω・cm、可視光透過率は53%であった。また、低周波電磁遮蔽部材15としては、実施例1と同じ導電メッシュ部材を用いた。高周波電磁遮蔽部材13及び低周波電磁遮蔽部材15を付与された絶縁板11は、スペーサ40を介在させることにより離間して配置した。これにより絶縁板11間には、6mmの厚さの空気層50が形成された。スペーサ40と低周波電磁遮蔽部材15との接続に用いた接着層16の材質(ポリビニルブチラール)や、ガラス板の大きさなどは、前述した実施例1と同様である。
実施例2として、第2の実施の形態の構造を備える電磁遮蔽パネル100aを製作した。使用した材料は実施例1と概略同じである。異なる点は、被挟持絶縁体22を構成するガラス板を3mmのものとする一方で枚数を2枚としたこと、及び、それら2枚の被挟持絶縁体22の中間に更に被挟持高周波電磁遮蔽部材24として酸化錫膜を設けたことである。その他の構成については上述した実施例1と同様である。
実施例3として、第3の実施の形態の構造を備える電磁遮蔽パネル100bを製作した。使用した材料は実施例1と概略同じである。異なる点は、実施例1の高周波電磁遮蔽部材13を、可視光透過率81%の導電フィルム17に置き換えたことである。ここで、導電フィルム17は、導電薄膜18と絶縁フィルム19を備えている。具体的には、導電薄膜は酸化インジウム錫膜であり、絶縁フィルム19はPETフィルムである。図示されているように、導電薄膜18は、絶縁フィルム19によって保護されている。なお、酸化インジウム錫膜の表面抵抗は2Ω・cmであった。その他の構成については、上述した実施例1と同様である。
