Abstract:
1. A method of manufacturing an electroconductive film subject to edge curl due to volume contraction after baking, comprising the steps of: sequentially repeating a film forming step of forming a film containing a photosensitive material and an electroconductive material therein and an exposure step of irradiating a light onto a desired region of said film formed in said film forming step to provide a latent image for a plurality of times to laminate each second or subsequent film layer on each previous film layer into a laminate film where the latent images of the respective layers are integrated into a laminate latent image; developing the latent image into a development image by removing a non-latent image region of said laminate film after the formation of said laminate film together; and baking said development image formed in said developing step, whereby the step of sequentially repeating the film-forming step and the exposure step counteracts the edge curl formed by volume contraction after the baking step.
