基体1を構成する材料は、透明な絶縁材料であれば特に限定されるものではなく、このような透明材料としては、例えばポリメタクリル酸メチル、ポリカーボネート、ポリエステル等の合成樹脂、およびガラスが挙げられる。
導電膜2は、上述した導電性高分子組成物から溶媒を除去することによって得られるものである。
PEDOT0.14質量%およびPSS26質量%の水分散液(アルドリッチ社製:製品番号560596)に、ジメチルスルホキシドからなる溶媒を水分散液100質量部に対して11質量部添加し、アルキルジフェニルエーテルジスルホン酸二ナトリウムからなる陰イオン性界面活性剤−1(商品名「ぺレックスSS−H」、花王(株)製)をPEDOTおよびPSSの合計100質量部に対して2.0質量部の割合となるように配合し、水分散液を25℃で0.25時間撹拌し、導電性高分子組成物を得た。この導電性高分子組成物をバーコーター(製品名:PI−1210自動塗工装置、テスター産業(株)製)を用いて、厚さ100μmのポリエチレンテレフタレート(PET)フィルム(東レ(株)製:商品名 ルミラーT60)上に塗布した後、130℃で5分間乾燥させ、溶媒を除去した。こうして、PETフィルム上に膜厚0.5μmの導電膜を形成し、導電体を得た。

陰イオン性界面活性剤−1を配合しなかったこと以外は実施例1と同様にして導電体を作製した。
陰イオン性界面活性剤−1をPEDOTおよびPSSの合計100質量部に対して0.3質量部配合したこと以外は実施例1と同様にして導電体を作製した。
陰イオン性界面活性剤−1をPEDOTおよびPSSの合計100質量部に対して6.4質量部配合したこと以外は実施例1と同様にして導電体を作製した。
