摘要

The present invention provides a positive type radiation-sensitive resin composition for producing a product formed by plating, which is capable of forming a product formed by plating of a thick film such as a bump or a wiring with high precision and has excellent sensitivity and resolution, and a process for producing a product formed by plating using the composition. The positive type radiation-sensitive resin composition for producing a product formed by plating comprises (A) a polymer having an acid-dissociative functional group which is dissociated by an acid to generate an acid functional group and (B) a component which generates an acid when irradiated with a radiation. This composition is used also for a positive type radiation-sensitive resin film. The product formed by plating is produced by a process including a step wherein electroplating is carried out with the use of a pattern that is formed from the composition or the resin film on the substrate as a mold.
