Description
図1ないし図3に示すように、本発明を実施した導電性フィルム10は、メッシュ状に形成されており、網目としての開口が面状(二次元)に複数並んでいる。導電性フィルム10は、フィルム基材11と、導電材料層12とを備える。導電材料層12は、フィルム基材11の一方のフィルム基材面(以下、第1基材面と称する)11aに層状に設けられて一方のフィルム面を成し、導電材料で形成された部材である。なお、図1には、導電性フィルム10の導電材料層12側を図示しており、図2,図3では、フィルム基材11の厚みに対して導電材料層12の厚みを誇張して描いてある。導電性フィルム10を貼り付け対象物に対して貼り付ける場合には、フィルム基材11が貼り付け対象物に接し、導電材料層12が外側に露呈するように、導電性フィルム10を配する。なお、導電性フィルム10の厚みは、フィルム基材11の厚みT11と導電材料層12の厚みT12との和であり、図2及び図3においては符号T10を付す。
図17Aに示す導電性フィルム70は、フィルム基材71と、導電材料層80とを備える。導電材料層80は、フィルム基材71の第1基材面a上に、層状に重ねて設けられている。この導電性フィルム70にも導電性フィルム10と同様に、フィルム基材71と導電材料層80とを、厚み方向に貫通する貫通孔75(図17B参照)が形成されているが、図17Aにおいては貫通孔75の図示を略してある。なお、図17Aは、導電性フィルム70を模式的に示すものであり、各フィルム面を便宜的に平坦に描いてある。
図18を参照しながら、第3実施形態である導電性フィルム90について説明する。なお、図18においては、図1に示す部材と同じものには、図1と同じ符号を付し、説明を略す。また、図の煩雑化を避けるため、貫通孔13については図示を略してある。導電性フィルム90は、フィルム基材11と、導電材料層12と、ゲル層91とを備える。ゲル層91はフィルム基材11の第2基材面11bに配されている。ゲル層91は、第2基材面11bに形成されている基材開口部11c(図示無し)を閉塞するように第2基材面11bを覆っている。
