1265000 (1) 玖、發明說明 【發明所屬之技術領域】 本發明，是有關構成釣竿的竿體，特別是，將合成樹 脂含浸於碳纖維或玻璃纖維等的強化纖維而成的預浸料素 材所構成的竿體、及竿體的製法。 [先前技術】 使用於魚釣魚的釣竿的竿體，一般，是將環氧樹脂等 肇 的合成樹脂含浸於稱爲預浸料的強化纖維加工成墊片狀、 帶狀的預浸料素材呈芯材捲繞後，加以煅燒製造而成。從 這種預浸料素材所製造的竿體，因爲輕、物理強度優秀及 具有適度的彎曲性，所以可充分發揮釣竿特性。 ' 一般釣竿是嗜好品·休閒用品，在其表面的模樣·色 _ 彩等的外觀要求具有個性的特性。在此，也提供在竿體的 周面蒸著金屬乃至塗抹施加金屬電鍍來表現如金屬的光澤 •色澤等的竿體。 籲 【發明內容】 (本發明所欲解決的課題） 但是，如周知，釣竿是進行釣魚時上擬餌的魚拉伸竿 體的話會大彎曲，大的折曲力或在周方向朝施加破壞竿體 的方向的力量會增加。這種力是施加於竿體的話，在竿本 體本身的周面會產生細的破裂·裂縫。而且，這種細的破 裂·裂縫是在其周面上特別是在發出光澤的金屬電鍍會被 (2) 1265000 強調，若長期使用釣竿的話，外觀上破裂裂縫明顯。 本發明的課題，是提供一種即使長期使用表面的細破 裂·裂縫等也不明顯，並可表現良好的光澤·色彩的竿體 (用以解決課題的手段） 發明1的竿體，具備：將合成樹脂含浸於碳纖維或玻 璃纖維等的強化纖維的複數預浸料素材加以層疊，其最外 靥是將合成樹脂含浸於玻璃纖維的強化纖維玻璃纖維預浸 料所組成的竿本體、及層疊於前述竿本體的周面的合成樹 脂層、及將陶瓷物理蒸著於前述合成樹脂層的周面的陶瓷 層、及層疊於前述陶瓷層的周面的透明層。 在此竿體中，比較上纖維本身的伸度豊富的玻璃纖維 預浸料是構成竿本體的最外層，即使在竿體加上大的折曲 力等破裂等也不易發生，假設發生破裂等也不易進一步擴 大。一方面，提高竿本體的周面的新式樣效果的層是將硬 度優秀的陶瓷物理蒸著在合成樹脂層，其本身產生破裂機 會是非常小。 且，對於這種竿體的製造過程中，爲了將陶瓷物理蒸 著於竿體周面而需要將被蒸著面平滑化，雖由合成樹脂層 將竿本體周面平滑化，是進一步爲了將竿本體周面本身平 滑化也需要硏磨表面加工。此時，因爲竿本體的周面是由 比較上硬度小的玻璃纖維預浸料所構成，所以表面硏磨加 工也容易。 -6 - (3) 1265000 發明2的竿體，如發明1的竿體，其中，前述陶瓷層 是C r N、T i N、T i 0 2等的金屬氮化物或是金屬氧化物。 在此竿體中，藉由設置由CrN、TiN、Ti02等的金屬 氮化物或是金屬氧化物所構成的陶瓷層，可以充分提高其 本身的強度，且表現美的光澤·色澤等，可以充分提高新 式樣效果。 發明3的竿體，如發明1或2的竿體，其中，前述竿 本體的外表面，是具有碳纖維是朝周方向的碳纖維預浸料 、及層疊於其外周的周方向的玻璃纖維玻璃纖維預浸料所 構成。 在此竿體的竿本體的最外周面雖設置如上述玻璃纖維 預浸料，但是如周知玻璃纖維與碳纖維相比彈性率差。因 此’竿體的周方向的剛性是有不足的情況。在此，在與其 內周鄰接配置的周方向將碳纖維拉聚的碳纖維預浸料，是 充分互補只有玻璃纖維預浸料的幾分不安的竿體的周方向 的剛性，提高竿體的剛性。 發明4的竿體，如發明3的竿體，其中，前述玻璃纖 維預浸料是平均厚度0.010〜0.0 2 0mm程度的預浸料素材 〇 在此竿體中，預定的碳纖維预浸料是鄰接在玻璃纖維 預浸料的內側，玻璃纖維預浸料本身不需要厚厚地層疊， 可以防止表面的細的破裂的程度即可。具體上，玻璃纖維 預浸料具有預定的範圍程度的厚度即可，有利於竿體本身 的輕量化。 -7 - (4) 1265000 且，本發明的竿體，是在竿本體的外側，設有物理蒸 著陶瓷的陶瓷層。 在如此的竿體中，因爲陶瓷層是比金屬硬，所以其陶 瓷層不易刮傷，細的破裂或裂縫也不易產生。且’可以獲 得與金屬層的情況同樣美的光澤、發色。因此，長期使用 也可以維持良好的光澤、色彩。 且，強化纖維藉由煅燒包含碳纖維的纖維強化合成樹 脂材而形成竿本體的情況，在該竿本體的外側中，設有下 側陶瓷層及上側陶瓷層，下側陶瓷層是呈單色發色’上側 陶瓷層是呈彩虹色發色較佳。且，在纖維強化合成樹脂材 中有例如預浸料素材。 包含碳纖維的情況時，雖藉由煅燒使竿本體因碳纖維 而成爲黑色，該情況，藉由使另外單色發色的下側陶瓷層 位在彩虹色發色的上側陶瓷層的內側之間，因爲黑色的竿 本體是由下側陶瓷層所覆蓋，與無設置下側陶瓷層的情況 相比，上側陶瓷層的彩虹色的發色良好。 且，強化纖維藉由煅燒包含碳纖維的纖維強化合成樹 脂材而形成竿本體的情況，在該竿本體的外側，透過黑色 的合成樹脂層設有前述陶瓷層較佳。在竿本體的表面只有 碳纖維的部分特別是黑色明顯的情況，因爲其竿本體的表 面是藉由黑色的合成樹脂層覆蓋，均一的黑色之外並形成 有陶瓷層，因此，不會成爲稀疏模樣而可以確保良好的陶 瓷層的發色。且，在纖維強化合成樹脂材中有例如預浸料 素材。 -8- (5) 1265000 且，本發明的竿體的製法，是在竿本體的外側，藉由 賤射形成陶瓷層。 在該製法中，因爲是藉由賤射形成陶瓷層，其他的方 法，例如，與由離子鍍膜形成的方法相比’可以容易形成 均一厚度的陶瓷層。陶瓷層的厚度不均一的話，雖無法形 成良好的單色的陶瓷層，但是藉由賤射形成陶瓷層就可獲 得均一厚度的陶瓷層，可以容易獲得發出良好單色陶瓷層 ❿ 特別是，中間電極是使用金屬氮化物，形成由金屬氮 化物所構成的陶瓷層較佳。形成由金屬氮化物所構成的陶 瓷層的情況，也考慮藉由將非氮化物的單體的金屬與氮氣 (反應性氣體）反應並藉由蒸著金屬氮化物的反應性離子 鍍膜法形成，是在反應性離子鍍膜中形成由良好的金屬氮 化物所構成的陶瓷層是困難的。對於此，藉由進行將金屬 氮化物本身作爲中間電極賤射，朝可以將由良好的金屬氮 化物構成的陶瓷層形成強力且均一的厚度。 馨 且，該情況，因爲中間電極是使用金屬氮化物的燒結 體，所以可以便宜形成金屬氮化物的陶瓷層。 【實施方式】 〔第1實施例〕 以下，對於本發明的第1實施例參照圖面說明。 (釣竿整體的構造） -9- (6) 1265000 如第1圖所示，採用本發明的第1實施例的釣竿，是 具有：筒狀的基竿1、及在基竿1的尖端側由依序伸出的 形式連結的複數筒狀的中竿2、3、及與前述中竿3的尖 端側連結的尖端竿4。這些的基竿1〜尖端竿4，是如後 述’由碳纖維強化樹脂、玻璃纖維強化樹脂等構成的預浸 料墊片·預浸料帶所形成的先端較細錐的筒狀構件。 在基竿1的竿基側端部中屁股栓9是可裝卸自如地嵌 入’在周面中將捲線器可裝卸自如地裝設。由此實施例說 明的釣竿是中通過竿’在基竿1的捲線器座5的尖端側周 面形成將來自捲線器的釣線導入至竿體內部用的釣線導入 口 6，在其周面中將釣線導引至釣線導入口內。 一方面’在尖端竿4的尖端側端部連結有頂導引8， 從釣線導入口 6導引至竿體內部的釣線是依序送出至尖端 側並從頂導引8導出至外部。 (中竿2的構造及製造方法） 將各竿體的構造及製造方法，以中竿2爲例說明。 如第2圖所示，中竿2，是將環氧樹脂等的合成樹脂 含浸於碳纖維的碳纖維強化樹脂，或將環氧樹脂等的合成 樹脂含浸於玻璃纖維的玻瑀纖維強化樹脂等所構成的預浸 料墊片·預浸料帶依序層疊。而且，在其周面物理蒸著陶 瓷。 具體上，具有··從複數的預浸料墊片·預浸料帶所構 成的竿本體1 0、及層疊於竿本體1 0的周面的合成樹脂層 -10- (7) 1265000 1 1、及物理蒸著於合成樹脂層1 1的周面的陶瓷層1 2、及 層疊於陶瓷層1 2的周面的透明層1 3。 竿本體1 〇，對於後述的製造方法，進一步詳細說明 其構造，是由本體基層15、及層疊於本體基層15的周面 的外表面層1 6所組成。而且，此外表面層1 6是更由碳纖 維預浸料層1 7及玻璃纖維預浸料層i 8所組成。 合成樹脂層Η，是將竿本體1 〇的周面平滑化並將陶 瓷層1 2的物理蒸著容易且充分用的層，例如由環氧樹脂 或尿院樹脂等組成。且，合成樹脂層1 1 (基礎塗裝）不 限於一次塗裝的單層中而也可以是數次塗裝的多層。 陶瓷層12，是將CrN、TiN、Ti02等的金屬氮化物或 是金屬氧化物等的陶瓷例如藉由賤射或離子鍍膜等周知的 物理蒸著法密合層疊於上述的合成樹脂層1 1.。與使用非 氮化·氧化的單純金屬的情況相比，藉由使用陶瓷化使強 度·耐久性優秀。即，設在由非氮化·氧化的金屬所構成 的層的情況相比，陶瓷層1 2其硬度高，因此，具有刮傷 不易且細的破裂或裂縫也不易產生的優點。且，與由金屬 構成的層同樣可以獲得美的光澤、發色，可以表現良好的 光澤·色彩且新式樣效果也優秀。 透明層13，是保護陶瓷層12用的透明或是半透明的 合成樹脂層，依據需要附加適度的色彩也可以。且，透明 層13 (頂護膜）也不限於一次塗裝的單層中而也可以是 數次塗裝的多層。 接著，將竿本體1 0的製造方法依序說明，並說明其 -11 - (8) 1265000 構造。 如第3 ( a )圖所示，準備先端較細筒狀的蕊軸（芯 材）50，在其周面依據需要預先塗抹好可分離式劑等。而 且’例如’在小徑化尖端側端部或其他補強的需要處，部 分地捲繞補強用預浸料5 1。此補強用預浸料5 1是將碳纖 維·玻璃纖維任一的強化纖維朝蕊軸50的周方向拉聚的 預浸料。 接著’如第3 ( b )圖所示，在蕊軸5 〇及補強用預浸 料5 1的外周朝軸方向將無間隙地呈螺旋狀加工成帶狀的 預浸料帶5 2捲繞。例如，此預浸料帶5 2是在帶的長度方 向將碳纖維拉聚帶寬5〜8 m m程度，碳纖維的拉伸彈性率 是24〜50t/mm2程度較佳。 如第3 ( c )圖所示，將此預浸料帶5 2捲繞於其外周 ’進一步另外將預浸料墊片5 3捲繞。預浸料墊片5 3是依 據需要複數枚依序捲繞。此預浸料墊片5 3，是例如將碳 纖維朝蕊軸5 0的軸方向拉聚，與上述的預浸料帶5 2相比 具有大的碳纖維的拉伸彈性率的30〜60t/mm2程度較佳。 將複數枚預浸料墊片5 3捲繞的情況中，有關於捲繞的各 別的預浸料墊片5 3的碳纖維的特性也可以不同。然而， 到此爲止的各預浸料帶·墊片是形成如第2圖所示的竿本 體1 0的本體基層1 5的結構。 如第3 ( d )圖所示，在如此捲繞的預浸料墊片5 3的 外周，進一步，碳纖維是將朝帶的長度方向拉聚的預浸料 帶54呈螺旋狀捲繞。此預浸料帶54，是與上述的預浸料 -12- (9) 1265000 帶52同樣寬5〜8mm程度，碳纖維的拉伸彈性率是比較 小的2 4〜3 0 t / m m2程度較佳。此預浸料帶5 4是形成如第 2圖所示的外表面層1 6的碳纖維預浸料層1 7。 如第3 ( e )圖所示，進一步在其外周，捲繞有將玻 璃纖維朝蕊軸5 0的周方向及軸方向雙方織入的玻璃預浸 料墊片5 5。 此玻璃預浸料墊片5 5的玻璃纖維與碳纖維相比拉伸 彈性率較小，爲6〜8 t/mm2程度。合成樹脂的含有量也比 較少較佳，例如，合成樹脂的含有率是2 0〜3 0 %程度。且 ，玻璃預浸料墊片5 5爲了輕量化比較薄地層疊較佳，可 以使用平均厚度0.0 1 0〜0.020mm程度。而且，此玻璃預 浸料墊片5 5是成爲第2圖的玻璃預浸料墊片層1 8。取代 玻璃預浸料墊片5 5，同樣地也可以捲繞將玻璃預浸料墊 片與預浸料帶52、54同樣呈寬5〜8mm程度開縫的帶狀 的預浸料帶。 如此將各預浸料墊片·帶依序捲繞，如第3 ( f)圖 所示’在需要處進一步將補強用預浸料5 6部分地捲繞， 在其外周將由聚丙烯、聚酯等的合成樹脂所構成的成型帶 5 7呈螺旋狀被施加張力的狀態下進行捲繞。此補強用預 浸料5 6，是例如，對於如基竿丨的釣線導入口 6處供補 強用或竿體的卡合部分補強用而捲繞，也可以使用編入耐 綸纖維後含浸合成樹脂的預浸料等。 將這些各預浸料在爐內煅燒。由此各預浸料被一體化 。接著’剥離成型帶5 7，拔除蕊軸5 0，切齊兩端調整成 -13- (10) 1265000 適當的長度，硏磨周面平滑化來製造竿本體10。 之後’如已述’將合成樹脂塗抹在周面設置合成樹脂 層1 1進一步將周面平滑化，物理蒸著陶瓷構成陶瓷層i 2 ，設置透明層13製造中竿2等的竿體。 且’對於由物理蒸著陶瓷層1 2形成過程朝詳細說明 的話’物理蒸著之中特別是藉由賤射或是離子鍍膜形成較 佳，可以獲得高密度針孔少的陶瓷層1 2。 且，藉由賤射形成特佳。即，在離子鍍膜的情況中因 爲將陶瓷附著由鎢等構成的電極（燈絲），所以鎢也稍微 蒸發附著於竿本體1 0，該部分會使陶瓷層1 2的純度下降 。對於此，在賤射的情況中，因爲可以將成爲中間電極的 陶瓷就這樣地附著，所以具有容易獲得純度的高陶瓷層 1 2的優點。 且，在賤射的情況中也有容易形成均一厚度的陶瓷層 1 2爲優點。例如，想獲得良好的單色的發色情況中，雖 需要將陶瓷層12的厚度高精度且均一地形成，但是在離 子鍍膜的情況中厚度的控制是非常困難，而在賤射的情況 中可以容易獲得均一厚的陶瓷層1 2，因此可以獲得良好 的單色的陶瓷層12。且，例如，鉻氮化物（CrN，Cr2N) 的情況中可獲得銀灰或是銀色的金屬色，鈦氮化物（TiN )可獲得金色的金屬色（即黃金色）。 且，陶瓷層1 2是金屬氮化物的情況，因爲可由賤射 獲得純度高的陶瓷層1 2 ’使單色的發色更佳’形成均一 厚的同時可以獲得良好的發色。特別是金屬氮化物之中在 -14- (11) 1265000 鉻氮化物的情況中與賤射的相性佳，可以將由純度高的鉻 氮化物所構成的陶瓷層1 2高密合性且均勻地附著。 在此，對於由賤射形成陶瓷層1 2的方法，以形成由 鉻氮化物所構成的陶瓷層1 2的情況爲例作說明。首先， 中間電極是使用鉻氮化物（例如CrN )，特別是，使用鉻 氮化物的燒結體。例如，也考慮與將鉻作爲反應性氣體的 氮氣反應形成的鉻氮化物所構成的陶瓷層1 2的方法，在 其方法中形成由鉻氮化物所構成的陶瓷層1 2並不容易。 對於其，藉由使用作爲中間電極鉻氮化物，可以容易形成 高純度的由鉻氮化物所構成的陶瓷層1 2。且，使用燒結 體的話可以抑制製造成本。 如此進一步說明由鉻氮化物所構成的陶瓷層1 2由賤 射形成方法的一例的話，此賤射裝置，是在真空容器的外 壁安裝有中間電極，同時使竿本體10在真空容器內一邊 自轉一邊周旋轉。即，竿本體1 〇是在中間電極前方周旋 轉，同時自轉。使用這種賤射裝置，將其真空容器排氣7 xl0_5 Torr爲止，在該真空容器內將氮氣體導入至3x 1〇'4爲止，接著，在該真空容器內將氬氣導入至3xl(T3 爲止。而且，將與成爲對象物的竿本體1 〇周旋轉、自轉 的同時在竿本體1 〇外加直流電力，在中間電極使用鉻氮 化物進行賤射。例如，將2.5Α X 6 00V ( =1.5KW)的直流 電力20分間外加，鍍膜膜厚600 的鉻氮化物的膜。且 ，也可導入氮氣。 如此製造的中竿2等的竿體，玻璃預浸料墊片層18 -15- (12) 1265000 是構成竿本體1 0的最外層，即使在竿體加上大的折曲力 等也不易發生破裂等，即使假設破裂等發生也不易進一步 拆擴大。一方面，CrN、TiN、Ti02等的金屬氮化物或是 由金屬氧化物所構成的陶瓷層1 2是物理蒸著成合成樹脂 層1 1，在其本身產生破裂的機會是非常小。因此，從竿 本體1 〇可以充分防止在其周面產生破裂裂縫等而損失外 觀。且，這種竿本體1 0的最外層是玻璃預浸料墊片層1 8 ，硏磨加工容易，且也因陶瓷的物理蒸著而使周面容易平 滑化。 且，竿本體10的外表面層16是由碳纖維預浸料層 1 7及玻璃纖維預浸料層1 8所構成，由玻璃纖維預浸料層 1 8的內周使碳纖維是朝周方向被拉聚的碳纖維預浸料層 1 7可互補周方向的剛性，藉由比較上薄的玻璃纖維預浸 料層1 8可以充分維持竿體的折曲強度。 〔其他的實施例〕 上述實施例說明製造方法只是一例，形成作爲竿本體 1 0的外表面層1 6的方法，也可以例示如以下的方法。 (a)如第4圖所示，在竿本體1〇的本體基層15將 該部分由預定的預浸料形成後，在其外周準備將碳纖維朝 蕊軸5 0的周方向拉聚的碳預浸料墊片6 4進行捲繞。而且 ，將玻璃預浸料墊片65捲繞於其外周。此玻璃預浸料墊 片6 5是與上述實施例相異，玻璃的方向是對於蕊軸5 〇傾 斜的交差方向編入也可以。此情況，將朝周方向拉聚的碳 -16- (13) 1265000 預浸料墊片6 4的捲完的連接處，藉由覆蓋玻璃預浸料墊 片6 5，就有可以防止表面層的破裂的效果。 (b)如第5圖所示，在竿本體ι〇的本體基層15將 該部分由預定的預浸料形成後，在其外周準備將碳纖維朝 蕊軸5 0的周方向拉聚的碳預浸料墊片7 4進行捲繞。而且 ’也可考慮在其外周將玻璃預浸料帶呈螺旋狀依序捲繞。 且’形成外表面層1 6時，也有如上述實施例捲繞碳 纖維預浸料墊片形成碳纖維預浸料層1 7後，將玻璃預浸 料塾片壬螺旋狀捲繞形成玻璃纖維預浸料層1 8的方法。 進一步，由碳纖維預浸料帶形成碳纖維預浸料層1 7，捲 繞玻璃預浸料帶形成玻璃纖維預浸料層1 8也可以。 (c )碳預浸料墊片74是使用將碳纖維朝蕊軸5 0的 軸方向拉聚者也可以。 且，在上述實施例中，是以竿本體1 〇的最外層爲玻 璃纖維預浸料組成者作說明，但是對於竿本體1 0的結構 也可作各種變更。 例如，如第6圖所示的中竿2 (竿體）的竿本體1 〇， 是與第2圖的結構同樣是由本體基層15及層疊於該本體 基層1 5的外周面的外表面層1 6所構成，是在外表面層 1 6不具有玻璃纖維預浸料層1 8的部分是與第2圖的結構 相異。即，如第6圖所示的竿本體1〇，其外表面層16整 體是由碳纖維預浸料層所構成。如此’竿本體1 〇的層構 造是可作各種變更’對於強化纖維也可適當變更。但是， 竿本體1 0的主的結構’在最內層是使強化纖維朝周方向 -17- (14) 1265000 被拉聚，在竿本體1 0的主部中間層，強化纖維是朝竿本 體1 〇的軸方向被拉聚，在最外層是使強化纖維朝周方向 被拉聚的結構。 但是，將如第6圖所示的竿體進一步詳細說明的話， 該竿體，是在竿本體1 0的外側，透過透明的合成樹脂層 1 1，將陶瓷層設成多層。具體上，陶瓷層1 2，是由下側 陶瓷層122及上側陶瓷層121所構成，下側陶瓷層122是 層疊於合成樹脂層1 1的外周面，上側陶瓷層1 2 1是層疊 於下側陶瓷層1 22的外周面。而且，在上側陶瓷層1 2 1的 外周面中與上述的同樣設有透明層1 3。 下側陶瓷層1 22及上側陶瓷層1 2 1也可爲同種的陶瓷 ，但是異種的陶瓷較佳。例如，下側陶瓷層1 22可爲金屬 氮化物，上側陶瓷層1 2 1可爲金屬氧化物。金屬氮化物如 CrN，而金屬氧化物如Ti02。 如此將由金屬氧化物所構成的上側陶瓷層1 2 1及由金 屬氮化物所構成的下側陶瓷層1 22層疊的情況中，將兩層 1 2 1、1 22同時由賤射形成當然可以，但是將金屬氮化物 由賤射蒸著，同時將金屬氧化物由離子鍍膜蒸著事也可以 〇 即，下側陶瓷層1 22爲金屬氮化物的情況時將其由賤 射形成，上側陶瓷層1 2 1爲金屬氧化物的情況時將由其離 子鍍膜（特別是反應性離子鍍膜）形成。如此形成的情況 中，由賤射形成均一厚度的下側陶瓷層1 2 2可先獲得良好 的單色的發色。進一步，藉由離子鍍膜，可以形成厚度複 -18- (15) 1265000 雜變化的上側陶瓷層1 2 1，由此藉由千渉可以獲得呈彩虹 色發色的上側陶瓷層1 2 1。如此形成二層的陶瓷層1 2 1、 122的話，整體是藉由上側陶瓷層12 1使竿體本身呈彩虹 色發色。且，下側陶瓷層12 2是由賤射形成鉻氮化物（ CrN )，上側陶瓷層121是由離子鍍膜形成Ti02的情況’ 竿體整體，是呈彩虹色發色的金屬色。 如此形成由離子鍍膜呈彩虹色發色的陶瓷層情況中’ 在其竿本體10上直接，或者，在合成樹脂層11上直接形 成也可以，例如，在合成樹脂層1 1上形成如上述的下側 陶瓷層1 2 2較佳。 即，藉由在呈彩虹色發色的上側陶瓷層1 2 1的內側設 置呈單色發色的下側陶瓷層1 22，就可使彩虹色的發色更 佳。在竿本體1 〇的強化纖維含有碳纖維情況，由煅燒（ 加熱硬化）使竿本體1 〇因碳纖維成爲黑色。因此，在其 黑色的竿本體1 0的外側只設有呈彩虹色將發色陶瓷層的 情況中，基礎因爲是黑色而有彩虹色的發色不佳情況。對 於其，在上側陶瓷層1 2 1的內側藉由設置下側陶瓷層1 22 ，因爲藉由單色的下側陶瓷層122使黑色的竿本體10被 覆蓋，所以位置於其外側的上側陶瓷層1 2 1的彩虹色的發 色良好。且，上側陶瓷層1 2 1是單色的情況，在其內側藉 由設置下側陶瓷層1 22，也可使上側陶瓷層1 2 1的發色良 好。 且，在第5圖的例中，陶瓷層12是上下二層，當然 三層以上也可以。 -19- (16) 1265000 且，將作爲強化纖維的碳纖維至少使用於一部分的竿 本體1 〇的情況，將合成樹脂層1 1成透明以外，例如，作 成黑色的合成樹脂層11也可以。在竿本體10的外周面， 碳纖維的部分只有是特別是黑色明顯的情況中，藉由設置 這種黑色的合成樹脂層1 1，使設置於其外側的陶瓷層1 2 的發色不會因碳纖維的影響而降低較佳。 其他，竿體雖是以筒狀的中竿2爲例作說明，但是例 如，中實狀的竿體也可以。 〔發明的效果〕 依據本發明，可以提供可長期維持優秀光澤·色澤等 的外觀的釣竿。 【圖式簡單說明】

in which a synthetic fish is impregnated with a reinforcing fiber such as carbon fiber or glass fiber. The method of making the carcass and carcass. [Prior Art] The body of a fishing rod used for fish fishing is generally obtained by impregnating a synthetic resin such as epoxy resin into a reinforced fiber called a prepreg into a gasket-like, strip-shaped prepreg material. After the core material is wound, it is produced by calcination. The carcass made from such prepreg material has excellent fishing performance due to its light weight, excellent physical strength and moderate flexibility. 'General fishing rods are hobby goods and leisure products, and the appearance of the surface, color, color, etc. on the surface is required to have individual characteristics. Here, it is also provided to vaporize a metal on the peripheral surface of the body or to apply a metal plating to express a body such as a gloss or a color of the metal. OBJECT OF THE INVENTION (Problems to be Solved by the Invention) However, as is well known, the fishing rod is a large bending force when the fish is stretched on the fish when fishing, and a large bending force or a damage is applied in the circumferential direction. The strength of the body's direction will increase. When this force is applied to the carcass, fine cracks and cracks are generated on the peripheral surface of the body itself. Moreover, such fine cracks and cracks are emphasized on the circumferential surface of the metal plating, especially in the case of gloss. (2) 1265000. If the fishing rod is used for a long time, the crack in the appearance is obvious. An object of the present invention is to provide a smear body which is excellent in gloss and color even if it is not used for a long period of time, and which exhibits good gloss and color (the means for solving the problem). The synthetic resin is laminated on a plurality of prepreg materials of reinforcing fibers such as carbon fibers or glass fibers, and the outermost layer is a ruthenium body composed of a reinforced fiber glass fiber prepreg impregnated with a synthetic resin in glass fibers, and laminated thereon. A synthetic resin layer on the circumferential surface of the crucible body, a ceramic layer in which the ceramic is physically vaporized on the circumferential surface of the synthetic resin layer, and a transparent layer laminated on the circumferential surface of the ceramic layer. In this carcass, the glass fiber prepreg which is rich in the elongation of the fiber itself is the outermost layer of the body of the crucible, and it is hard to occur even if the carcass is broken by a large bending force or the like, and it is assumed that cracking occurs. It is also not easy to expand further. On the one hand, the layer which improves the new effect of the circumferential surface of the crucible body is to physically vaporize the ceramic having excellent hardness into the synthetic resin layer, and the cracking mechanism itself is very small. Further, in the manufacturing process of the carcass, in order to physically vaporize the ceramic on the peripheral surface of the carcass, it is necessary to smooth the surface to be vaporized, and the peripheral surface of the crucible body is smoothed by the synthetic resin layer, which is further Smoothing of the surface of the crucible body itself also requires honing surface processing. At this time, since the peripheral surface of the crucible body is composed of a glass fiber prepreg having a relatively small hardness, surface honing processing is also easy. The carcass of the invention 2, wherein the ceramic layer is a metal nitride such as C r N, T i N or T i 0 2 or a metal oxide. In the present invention, by providing a ceramic layer made of a metal nitride such as CrN, TiN, or TiO2 or a metal oxide, the strength of the metal layer can be sufficiently improved, and the gloss and color of the glass can be sufficiently improved. New style effect. The carcass of the invention of claim 3, wherein the outer surface of the body of the crucible is a carbon fiber prepreg having carbon fibers in a circumferential direction and a fiberglass fiberglass in a circumferential direction laminated on the outer periphery thereof. Prepreg is composed. Although the glass fiber prepreg is provided on the outermost peripheral surface of the crucible body of the crucible body, it is known that the glass fiber has a lower modulus of elasticity than the carbon fiber. Therefore, there is a shortage of rigidity in the circumferential direction of the carcass. Here, the carbon fiber prepreg in which the carbon fibers are pulverized in the circumferential direction disposed adjacent to the inner periphery thereof is sufficient to sufficiently complement the circumferential rigidity of the ridge body which is only a few points of the glass fiber prepreg, and to improve the rigidity of the corpuscle. The carcass of the invention of claim 4, wherein the glass fiber prepreg is a prepreg material having an average thickness of about 0.010 to 0.020 mm, wherein the predetermined carbon fiber prepreg is adjacent. On the inner side of the glass fiber prepreg, the glass fiber prepreg itself does not need to be thickly laminated, and the degree of fine cracking of the surface can be prevented. Specifically, the glass fiber prepreg may have a thickness within a predetermined range, which is advantageous for weight reduction of the carcass itself. -7 - (4) 1265000 Further, the body of the present invention is provided with a ceramic layer which is physically vapor-deposited on the outer side of the body. In such a carcass, since the ceramic layer is harder than the metal, the ceramic layer is less likely to be scratched, and fine cracks or cracks are less likely to occur. And it is possible to obtain the same gloss and color as the case of the metal layer. Therefore, it can maintain good gloss and color for long-term use. Further, the reinforcing fiber is formed by calcining a fiber-reinforced synthetic resin material containing carbon fibers to form a crucible body, and a lower ceramic layer and an upper ceramic layer are provided on the outer side of the crucible body, and the lower ceramic layer is in a single color. The color of the upper side ceramic layer is preferably iridescent. Further, in the fiber-reinforced synthetic resin material, for example, a prepreg material is used. In the case where the carbon fiber is contained, the crucible body is made black by the carbon fiber by calcination, and in this case, the lower ceramic layer of the monochromatic color is positioned between the inner side of the upper ceramic layer of the iridescent color. Since the black ruthenium body is covered by the lower ceramic layer, the iridescent color of the upper ceramic layer is better than that of the case where the lower ceramic layer is not provided. Further, in the case where the reinforcing fiber is formed by calcining a fiber-reinforced synthetic resin material containing carbon fibers to form a crucible body, it is preferable to provide the ceramic layer through the black synthetic resin layer outside the crucible body. In the case where only the portion of the carbon fiber is particularly black, the surface of the crucible body is covered by a black synthetic resin layer, and a uniform black layer is formed with a ceramic layer, so that it does not become a sparse appearance. It can ensure the color development of a good ceramic layer. Further, in the fiber-reinforced synthetic resin material, for example, a prepreg material is used. -8- (5) 1265000 Further, the carcass of the present invention is produced by forming a ceramic layer by sputtering on the outside of the crucible body. In this method, since the ceramic layer is formed by sputtering, other methods, for example, a ceramic layer having a uniform thickness can be easily formed as compared with the method of forming an ion plating film. If the thickness of the ceramic layer is not uniform, a good monochromatic ceramic layer cannot be formed, but a ceramic layer having a uniform thickness can be obtained by forming a ceramic layer by sputtering, and a good monochromatic ceramic layer can be easily obtained. It is preferable to use a metal nitride as the electrode to form a ceramic layer composed of a metal nitride. In the case of forming a ceramic layer composed of a metal nitride, it is also considered to be formed by reacting a metal of a non-nitride monomer with nitrogen (reactive gas) and reactive ion plating by vaporizing a metal nitride. It is difficult to form a ceramic layer composed of a good metal nitride in the reactive ion plating film. In this case, by performing the sputtering of the metal nitride itself as an intermediate electrode, a ceramic layer composed of a good metal nitride can be formed into a strong and uniform thickness. In addition, in this case, since the intermediate electrode is a sintered body using a metal nitride, a ceramic layer of a metal nitride can be formed inexpensively. [Embodiment] [First Embodiment] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. (Structure of the whole fishing rod) -9- (6) 1265000 As shown in Fig. 1, the fishing rod according to the first embodiment of the present invention has a cylindrical base 1 and a tip end side of the base 1 The plurality of cylindrical middles 2, 3 and the tip end 4 connected to the tip end side of the middle middle 3 are connected in the form of an extension. The base 1 to the tip end 4 are cylindrical members having a tapered front end formed of a prepreg gasket/prepreg composed of a carbon fiber reinforced resin, a glass fiber reinforced resin, or the like. The buttocks 9 are detachably fitted in the base side end portion of the base 1 and are detachably attached to the reel in the circumferential surface. In the fishing rod described in the above-described embodiment, the fishing line introduction port 6 for introducing the fishing line from the cord reel into the inside of the crucible body is formed on the tip end side peripheral surface of the reel holder 5 of the base 1 by the crucible. Guide the fishing line into the fishing line inlet. On the one hand, a top guide 8 is coupled to the tip end side of the tip end 4, and the fish line guided from the line introduction port 6 to the inside of the body is sequentially sent to the tip end side and is led out from the top guide 8 to the outside. . (Structure and Manufacturing Method of Zhongmu 2) The structure and manufacturing method of each carcass are described by taking Zhongyu 2 as an example. As shown in Fig. 2, the middle cymbal 2 is a carbon fiber reinforced resin obtained by impregnating a synthetic resin such as an epoxy resin with carbon fiber, or a glass fiber reinforced resin containing a synthetic resin such as an epoxy resin. The prepreg gasket and prepreg tape are laminated in sequence. Moreover, ceramics are physically steamed on the circumference of the surface. Specifically, the crucible body 10 composed of a plurality of prepreg pads and prepreg tapes, and a synthetic resin layer 10-(7) 1265000 1 1 laminated on the circumferential surface of the crucible body 10 are provided. And a ceramic layer 12 that is physically vaporized on the circumferential surface of the synthetic resin layer 11 and a transparent layer 13 that is laminated on the circumferential surface of the ceramic layer 12. The crucible body 1 is composed of a main body base layer 15 and an outer surface layer 16 laminated on the circumferential surface of the main body base layer 15 for a detailed description of the manufacturing method to be described later. Further, in addition, the surface layer 16 is composed of a carbon fiber prepreg layer 17 and a glass fiber prepreg layer i 8 . The synthetic resin layer is a layer which smoothes the peripheral surface of the crucible body 1 and smoothes the physical evaporation of the ceramic layer 12, and is composed of, for example, an epoxy resin or a urine resin. Further, the synthetic resin layer 1 1 (base coating) is not limited to a single layer to be applied once, and may be a plurality of layers coated several times. The ceramic layer 12 is formed by laminating a metal nitride such as CrN, TiN or TiO 2 or a metal oxide such as a metal oxide to the above-mentioned synthetic resin layer 1 by a physical vapor deposition method such as sputtering or ion plating. . . . In comparison with the case of using a non-nitriding/oxidizing simple metal, strength and durability are excellent by using ceramization. In other words, the ceramic layer 12 has a higher hardness than the case of a layer made of a non-nitriding/oxidizing metal, and therefore has an advantage that scratching is not easy and fine cracking or cracking is unlikely to occur. Further, as with the layer made of metal, beautiful gloss and color can be obtained, and good gloss and color can be expressed and the effect of the new style is excellent. The transparent layer 13 is a transparent or translucent synthetic resin layer for protecting the ceramic layer 12, and may be added with a moderate color as needed. Further, the transparent layer 13 (top film) is not limited to a single layer to be applied once, and may be a plurality of layers coated several times. Next, the manufacturing method of the crucible body 10 will be described in order, and the structure of -11 - (8) 1265000 will be described. As shown in Fig. 3(a), the core shaft 50 (core material) 50 having a thinner tip shape is prepared, and a separable agent or the like is applied to the peripheral surface as needed. Further, for example, the reinforcing prepreg 51 is partially wound around the small-diameter tip end portion or other reinforcing portion. The reinforcing prepreg 51 is a prepreg in which the reinforcing fibers of any one of the carbon fibers and the glass fibers are pulled toward the circumferential direction of the core shaft 50. Then, as shown in Fig. 3(b), the prepreg strip 5 2 is spirally processed into a strip shape without any gap in the axial direction of the core shaft 5 〇 and the reinforcing prepreg 51. . For example, the prepreg strip 5 2 has a carbon fiber tensile polymerization band of about 5 to 8 m in the longitudinal direction of the belt, and the carbon fiber has a tensile modulus of 24 to 50 t/mm 2 . As shown in Fig. 3(c), the prepreg strip 52 is wound around its outer periphery' and the prepreg spacer 53 is further wound. The prepreg spacers 5 3 are wound in series as needed. The prepreg spacer 53 is, for example, a carbon fiber that is pulled toward the axial direction of the core shaft 50, and has a tensile modulus of elasticity of 30 to 60 t/mm 2 which is larger than that of the prepreg strip 52 described above. The degree is better. In the case where a plurality of prepreg spacers 5 3 are wound, the characteristics of the carbon fibers of the respective prepreg spacers 5 3 to be wound may be different. However, each of the prepreg tapes and spacers up to this point has a structure in which the main body base layer 15 of the ruthenium body 10 shown in Fig. 2 is formed. As shown in Fig. 3(d), on the outer circumference of the prepreg spacer 53 thus wound, the carbon fiber is spirally wound around the prepreg belt 54 which is stretched in the longitudinal direction of the belt. The prepreg belt 54 is about 5 to 8 mm wide as the above-mentioned prepreg -12-(9) 1265000 belt 52, and the tensile modulus of the carbon fiber is relatively small to the extent of 2 4 to 3 0 t / m 2 . Preferably. This prepreg strip 54 is a carbon fiber prepreg layer 17 which forms the outer surface layer 16 as shown in Fig. 2. Further, as shown in Fig. 3(e), a glass prepreg spacer 5 for woven the glass fibers into both the circumferential direction and the axial direction of the core axis 50 is wound around the outer circumference. The glass fiber of the glass prepreg gasket 5 has a tensile modulus lower than that of the carbon fiber, and is about 6 to 8 t/mm2. The content of the synthetic resin is also less preferred. For example, the content of the synthetic resin is about 20 to 30%. Further, the glass prepreg spacers 5 5 are preferably laminated thinly for light weight, and an average thickness of about 0.01 to 0.020 mm can be used. Further, the glass prepreg spacer 55 is the glass prepreg spacer layer 18 of Fig. 2 . Instead of the glass prepreg spacer 5, a strip-shaped prepreg tape having a glass prepreg spacer similar to the prepreg strips 52, 54 and having a width of 5 to 8 mm can be wound in the same manner. Thus, each prepreg gasket and tape are wound in this order, as shown in Fig. 3(f), and the reinforcing prepreg 56 is further partially wound at a desired place, and the outer periphery thereof will be made of polypropylene, poly The molding tape 57 composed of a synthetic resin such as an ester is wound in a state in which tension is applied in a spiral shape. The reinforcing prepreg 56 is, for example, wound for reinforcing the reinforcing portion or the engaging portion of the body at the fishline introduction port 6 of the base, and may be impregnated after being knitted with nylon fibers. Prepreg of resin, etc. Each of these prepregs is calcined in a furnace. Thereby, each prepreg is integrated. Next, the peeling-molding tape 5, 7 is removed, and the ends are adjusted to a suitable length of -13-(10) 1265000, and the honing surface is smoothed to produce the crucible body 10. Then, as described above, the synthetic resin is applied to the peripheral surface of the synthetic resin layer 1 to further smooth the peripheral surface, and the ceramic layer i 2 is physically vapor-deposited, and the transparent layer 13 is provided to produce a ruthenium or the like. Further, in the case where the physical vapor deposition ceramic layer 12 is formed in a detailed manner, it is preferable to form a ceramic layer 12 having a small density of pinholes, particularly by sputtering or ion plating. Moreover, it is particularly good by jetting. That is, in the case of the ion plating film, since the ceramic is adhered to an electrode (filament) made of tungsten or the like, the tungsten is also slightly evaporated and adhered to the crucible body 10, and this portion lowers the purity of the ceramic layer 12. In this case, in the case of sputtering, since the ceramic which becomes the intermediate electrode can be attached in this way, there is an advantage that the high ceramic layer 12 having a purity can be easily obtained. Further, in the case of sputtering, it is also advantageous to form a ceramic layer 1 2 having a uniform thickness. For example, in the case of obtaining a good monochromatic color, it is necessary to form the thickness of the ceramic layer 12 with high precision and uniformity, but in the case of ion plating, thickness control is very difficult, and in the case of sputtering. A uniform thick ceramic layer 12 can be easily obtained, so that a good monochromatic ceramic layer 12 can be obtained. Further, for example, in the case of chromium nitride (CrN, Cr2N), a silver ash or a silver metallic color can be obtained, and a titanium nitride (TiN) can obtain a metallic metallic color (ie, a gold color). Further, the case where the ceramic layer 12 is a metal nitride is preferable because a ceramic layer 1 2 ' having a high purity can be obtained by sputtering to make the color development of a single color more uniform, and a uniform color can be obtained. In particular, among the metal nitrides, in the case of -14-(11) 1265000 chromium nitride, the phase property with the sputtering is good, and the ceramic layer 12 composed of the chromium nitride having high purity can be adhered to the film with high adhesion and uniformity. . Here, a case where the ceramic layer 12 is formed by sputtering is described as an example in which a ceramic layer 12 composed of a chromium nitride is formed. First, the intermediate electrode is a sintered body using chromium nitride (e.g., CrN), in particular, chromium nitride. For example, a method of forming the ceramic layer 12 composed of a chromium nitride formed by reacting chromium as a reactive gas with nitrogen is also considered, and it is not easy to form the ceramic layer 12 composed of chromium nitride in the method. With regard to this, by using the chromium nitride as the intermediate electrode, it is possible to easily form the ceramic layer 12 composed of chromium nitride of high purity. Further, if a sintered body is used, the manufacturing cost can be suppressed. In the above description, the ceramic layer 12 made of chromium nitride is exemplified by a method of forming a sputtering apparatus in which an intermediate electrode is attached to the outer wall of the vacuum vessel, and the crucible body 10 is rotated in the vacuum vessel. Rotate on one side. That is, the crucible body 1 旋 is rotated around the front side of the intermediate electrode while rotating. Using this squirting device, the vacuum container was evacuated to 7 x 10 Torr Torr, and the nitrogen gas was introduced into the vacuum vessel to 3 x 1 〇 '4, and then argon gas was introduced into the vacuum vessel to 3 x 1 (T3). In addition, DC power is applied to the 竿 body 1 〇 while the 竿 body 1 to be the object is rotated and rotated, and chrome nitride is used for the middle electrode. For example, 2.5 Α X 6 00V (= 1.5 KW) DC power is applied for 20 minutes, and a film of chromium nitride having a thickness of 600 is applied. Nitrogen gas can also be introduced. The ruthenium of the 竿2, etc. thus produced, the glass prepreg spacer layer 18 -15- (12) 1265000 is the outermost layer that constitutes the body 10, and it is less likely to be broken or the like even if a large bending force is applied to the body, and it is difficult to further expand and expand even if a crack or the like occurs. On the one hand, CrN, TiN, The metal nitride of Ti02 or the like or the ceramic layer 12 composed of a metal oxide is physically vaporized into the synthetic resin layer 1, and the chance of cracking itself is very small. Therefore, it is sufficient from the crucible body 1 Prevent cracks from occurring on the circumference of the surface The outermost layer of the crucible body 10 is a glass prepreg spacer layer 18, which is easy to honing, and the peripheral surface is easily smoothed by the physical evaporation of the ceramic. The outer surface layer 16 of the body 10 is composed of a carbon fiber prepreg layer 17 and a glass fiber prepreg layer 18, and the carbon fibers are drawn in the circumferential direction by the inner circumference of the glass fiber prepreg layer 18. The carbon fiber prepreg layer 17 can complement the rigidity in the circumferential direction, and the bending strength of the carcass can be sufficiently maintained by comparing the thin glass fiber prepreg layer 18. [Other Embodiments] The above embodiment explains the manufacturing method. For example, a method of forming the outer surface layer 16 of the crucible body 10 may be exemplified as follows. (a) As shown in Fig. 4, the portion of the main body base layer 15 of the crucible body 1 is predetermined. After the prepreg is formed, a carbon prepreg gasket 64 which is prepared to pull the carbon fibers toward the circumferential direction of the core shaft 50 is wound around the outer periphery thereof. Further, the glass prepreg gasket 65 is wound around the carbon prepreg gasket 65. The outer periphery. This glass prepreg gasket 65 is different from the above embodiment, the square of the glass It is also possible to program the direction of intersection of the tilt of the core axis 5 。. In this case, the wound of the carbon-16-(13) 1265000 prepreg spacer 64 which is pulled in the circumferential direction is covered by the cover. The glass prepreg spacer 65 has an effect of preventing cracking of the surface layer. (b) As shown in Fig. 5, after the portion of the body base layer 15 of the crucible body ι is formed of a predetermined prepreg The carbon prepreg gasket 74 which is prepared to pull the carbon fibers toward the circumferential direction of the core shaft 50 in the outer periphery thereof is wound. Moreover, it is also considered that the glass prepreg strips are spirally wound on the outer circumference thereof. And when the outer surface layer 16 is formed, the carbon fiber prepreg layer is formed by winding the carbon fiber prepreg gasket as in the above embodiment, and the glass prepreg sheet is spirally wound to form a glass fiber. The method of prepreg layer 18. Further, a carbon fiber prepreg layer 17 is formed from a carbon fiber prepreg tape, and a glass fiber prepreg layer 18 is formed by winding a glass prepreg tape. (c) The carbon prepreg spacer 74 may be a member in which the carbon fibers are pulled toward the axial direction of the core axis 50. Further, in the above embodiment, the outermost layer of the crucible body 1 is composed of a glass fiber prepreg, but the structure of the crucible body 10 can be variously changed. For example, the 竿 body 1 〇 of the middle 竿 2 (竿 body) shown in Fig. 6 is the same as the structure of Fig. 2, and is composed of the body base layer 15 and the outer surface layer laminated on the outer peripheral surface of the body base layer 15. The configuration of the 16 is that the portion of the outer surface layer 16 that does not have the glass fiber prepreg layer 18 is different from the structure of Fig. 2. That is, as shown in Fig. 6, the outer surface layer 16 is entirely composed of a carbon fiber prepreg layer. In this way, the layer structure of the body 1 can be variously changed. The reinforcing fibers can be appropriately changed. However, in the innermost layer, the structure of the main body of the crucible body 10 is such that the reinforcing fibers are pulled in the circumferential direction -17-(14) 1265000, and in the middle portion of the main portion of the crucible body 10, the reinforcing fibers are the crucible body. 1 The axial direction of the crucible is pulled up, and the outermost layer is a structure in which the reinforcing fibers are pulled in the circumferential direction. However, as will be described in more detail in the carcass shown in Fig. 6, the carcass is formed on the outer side of the crucible body 10, and the ceramic layer is formed in a plurality of layers through the transparent synthetic resin layer 11. Specifically, the ceramic layer 12 is composed of the lower ceramic layer 122 and the upper ceramic layer 121, the lower ceramic layer 122 is laminated on the outer peripheral surface of the synthetic resin layer 11, and the upper ceramic layer 1-2 is laminated under The outer peripheral surface of the side ceramic layer 1 22 . Further, a transparent layer 13 is provided in the outer peripheral surface of the upper ceramic layer 1 21 as described above. The lower ceramic layer 1 22 and the upper ceramic layer 221 may also be the same kind of ceramic, but a different type of ceramic is preferred. For example, the lower ceramic layer 224 may be a metal nitride and the upper ceramic layer 221 may be a metal oxide. Metal nitrides such as CrN and metal oxides such as Ti02. In the case where the upper ceramic layer 1 2 1 made of a metal oxide and the lower ceramic layer 1 22 made of a metal nitride are laminated in this manner, it is of course possible to form the two layers 1 2 1 and 1 22 simultaneously by sputtering. However, when the metal nitride is vaporized by the ruthenium and the metal oxide is vaporized by the ion plating film, the lower ceramic layer 126 is formed by sputtering, and the upper ceramic layer is formed by sputtering. When 1 2 1 is a metal oxide, it is formed by an ion plating film (particularly, a reactive ion plating film). In the case of such formation, the lower side ceramic layer 1 2 2 having a uniform thickness by sputtering can obtain a good monochromatic color development first. Further, by the ion plating film, the upper ceramic layer 112 can be formed with a thickness of -18 - (15) 1265000, whereby the upper ceramic layer 1 2 1 having a rainbow color can be obtained by the Millennium. When the two-layer ceramic layers 1 2 1 and 122 are formed in this way, the entire body ceramic layer 12 1 is made to have a rainbow color. Further, the lower ceramic layer 12 2 is formed of chrome nitride (CrN) by sputtering, and the upper ceramic layer 121 is formed of TiO 2 by an ion plating film. The entire body is a metallic color which is iridescent. In the case where the ceramic layer having an iridescent color of the ion plating film is formed as described above, it may be directly formed on the crucible body 10 or formed directly on the synthetic resin layer 11, for example, formed on the synthetic resin layer 1 as described above. The lower ceramic layer 1 22 is preferred. Namely, by providing the lower side ceramic layer 1 22 which is monochromatic in color on the inner side of the upper side ceramic layer 1 2 1 which is iridescent, the iridescent color can be made better. In the case where the reinforcing fibers of the crucible body 1 have carbon fibers, the crucible body 1 is made black by the calcination (heat hardening). Therefore, in the case where only the enamel-colored ceramic layer is provided on the outer side of the black cymbal body 10, the base color is poor due to the black color and the rainbow color. For this, the lower ceramic layer 1 22 is provided on the inner side of the upper ceramic layer 1 2 1 because the black ruthenium body 10 is covered by the monochromatic lower ceramic layer 122, so that the upper side ceramic is positioned on the outer side thereof. The iridescent color of layer 1 2 1 is good. Further, in the case where the upper ceramic layer 1 21 is a single color, the lower ceramic layer 1 22 can be provided on the inner side thereof, and the upper ceramic layer 1 2 1 can also have a good color development. Further, in the example of Fig. 5, the ceramic layer 12 is two layers above and below, and of course three or more layers may be used. -19- (16) 1265000 In addition, when the carbon fiber as the reinforced fiber is used at least in part of the ruthenium body 1 ,, the synthetic resin layer 11 may be made transparent, and for example, a black synthetic resin layer 11 may be used. In the case where the carbon fiber portion of the outer peripheral surface of the crucible body 10 is only particularly black, the color of the ceramic layer 1 2 provided on the outer side of the ceramic layer 1 2 is not caused by the provision of the black synthetic resin layer 1 1 . The effect of carbon fiber is better. Others, although the carcass is described by taking the cylindrical middle jaw 2 as an example, for example, a medium-sized carcass may be used. [Effects of the Invention] According to the present invention, it is possible to provide a fishing rod which can maintain the appearance of excellent gloss, color, and the like for a long period of time.
