24 Claims

1. An electroconductive film comprising a first electroconductive part and a second electroconductive part,

wherein a surface of the second electroconductive part forms at least a part of a surface of the electroconductive film,

a surface of the first electroconductive part forms at least a part of a back face of the electroconductive film,

the first electroconductive part and the second electroconductive part each contain electroconductive fibers,

the electroconductive film further comprises a resin layer and a light-transmitting base material in this order from the first electroconductive part toward the second electroconductive part and between the first electroconductive part and the second electroconductive part,

the second electroconductive part directly contacts the light-transmitting base material, and

a difference between a surface resistance value of the second electroconductive part and a surface resistance value of the first electroconductive part is within ±30% of the surface resistance value of the first electroconductive part.
