Abstract

The present invention provides an actinic ray-sensitive or radiation-sensitive resin composition which is capable of forming a pattern having a low LWR and is further suppressed in the collapse of the formed pattern, a resist film, a pattern forming method, and a method for manufacturing an electronic device. The actinic ray-sensitive or radiation-sensitive resin composition of the present invention contains a photoacid generator represented by General Formula (1) or a resin having a residue obtained by removing one hydrogen atom from the photoacid generator represented by General Formula (1).
