Abstract
Disclosed is a conductive antireflection film comprising a laminate structure consisting of a conductive layer and an insulating covering layer covering the surface of the conductive layer and a conductive member connected at one end to the conductive layer and exposed at the other end to the outside. The conductive member is brought into contact with an electrolytic solution so as to control the state of the metal contained in the conductive layer, making it possible to prevent effectively an electromagnetic wave from leaking to the outside and to obtain a clear image of a high contrast.
