The pattern forming method includes (1) a step of forming a film using an actinic ray-sensitive or radiation-sensitive resin composition, (2) a step of exposing the film with actinic rays or radiation, and (3) a step of developing the exposed film using a developer containing an organic solvent, in which the actinic ray-sensitive or radiation-sensitive resin composition contains an acid-decomposable resin (1) having a repeating unit (a) having an aromatic ring and a repeating unit (b) represented by a specific general formula, and the content of the repeating unit (a) is 55% by mole or more with respect to all the repeating units of the acid-decomposable resin (1). The method for manufacturing an electronic device includes the pattern forming method.
