1. A conductive film substrate comprising:
- a. a substrate; and
b. a cured resin layer on the substrate, the cured resin layer comprising a first surface opposite the substrate, the first surface having a portion including a conductive film and a portion without a conductive film, wherein the portion of the cured resin layer including the conductive film comprises a cured portion projecting from the cured resin layer, the cured portion projecting the from the cured resin layer abutting the conductive film.

Abstract
A conductive pattern formation method of the present invention includes a first exposure step of radiating active light in a patterned manner to a photosensitive layer including a photosensitive resin layer provided on a substrate and a conductive film provided on a surface of the photosensitive resin layer on a side opposite to the substrate; a second exposure step of radiating active light, in the presence of oxygen, to some or all of the portions of the photosensitive layer not exposed at least in the first exposure step; and a development step of developing the photosensitive layer to form a conductive pattern following the second exposure step.
