Abstract

La présente invention vise à procurer un film conducteur transparent, par lequel d'excellentes caractéristiques incolores et transparentes peuvent être maintenues même si deux films conducteurs transparents sont stratifiés, et une section d'électrode en forme de motif peut être facilement formée. A cet effet, l'invention porte sur un film conducteur transparent, qui est caractérisé en ce qu'une couche d'oxyde de cérium, une couche à faible indice de réfraction transparente ayant un indice de réfraction supérieur ou égal à 1,4 mais inférieur à 1,7, et une couche conductrice transparente sont formées en séquence sur une surface d'un matériau de base de film transparent. La couche à faible indice de réfraction transparente est, de préférence, une couche de film mince constituée par un matériau en oxyde de silicium, et la couche conductrice transparente est, de préférence, une couche de film mince constituée par un matériau d'oxyde d'étain et d'indium.
