Abstract
Provided are an active-light-sensitive or radiation-sensitive resin composition having high DOF and excellent LWR, a pattern forming method using the composition, and a method for manufacturing an electronic device. The composition is an active-light-sensitive or radiation-sensitive resin composition containing a resin (P), in which the resin (P) includes a repeating unit (a) having a group that decomposes by the action of an acid to generate a polar group, including at least a specific repeating unit (a1) represented by General Formula (1); a repeating unit (b1) having at least one of a lactone structure, a sultone structure, or a carbonate structure; and a repeating unit (b2) having at least one of a lactone structure, a sultone structure, or a carbonate structure, which is different from the repeating unit (b1), the Ohnishi parameter of the repeating unit (b1) is larger than the Ohnishi parameter of the repeating unit (b2), and the difference between both the Ohnishi parameters is 0.85 or more.
