Abstract
A chemically amplified positive-type photosensitive resin composition capable of suppressing the occurrence of 'footing' in which the width of the bottom (the side proximal to the surface of a support) becomes narrower than that of the top (the side proximal to the surface of a resist layer) in the nonresist portion; and the generation of development residue when a resist pattern serving as a template for a plated article is formed on a metal surface of a substrate using the photosensitive resin composition. A mercapto compound having a specific structure is included in the photosensitive resin composition, and includes an acid generator which generates acid upon exposure to an irradiated active ray or radiation, and a resin whose solubility in alkali increases under the action of acid.
