PERFORATED METAL FOIL WITH SUBSTRATE, METHOD FOR MANUFACTURING PERFORATED METAL FOIL WITH SUBSTRATE, PERFORATED METAL FOIL, AND METHOD FOR MANUFACTURING PERFORATED METAL FOIL

摘要

Provided are a method for manufacturing perforated metal foil and perforated metal foil which achieve stable quality and improved production efficiency. Specifically provided is perforated metal foil with a substrate characterized by being provided with a substrate, a resist pattern portion on the surface of the substrate, the resist pattern portion being produced from a plurality of convex resists provided according to the pattern of through holes to be fabricated, and a metal plating layer provided by plating the surface of the substrate on the side on which the resist pattern portion is provided, wherein the thickness of the convex resist at the end of the outer peripheral edge thereof is thinner than the maximum thickness of the resist, and the metal plating layer is formed to extend onto the end of the outer peripheral edge of the resist.
