摘要

An actinic ray-sensitive or radiation-sensitive resin composition includes: (P) a resin that contains (A) a repeating unit capable of decomposing upon irradiation with an actinic ray or radiation to generate an acid in a side chain of the resin (P) and (C) a repeating unit represented by the following formula (I) as defined in the specification, wherein a polydispersity of the resin (P) is 1.20 or less.
