摘要

There is provided an actinic ray-sensitive or radiation-sensitive resin composition, having: (A) a resin having a repeating unit represented by formula (I); (B) a compound capable of generating an acid upon irradiation with an actinic ray or radiation; and (C) a resin having at least one repeating unit (x) out of a repeating unit represented by formula (II) and a repeating unit represented by formula (III) and containing substantially neither fluorine atom nor silicon atom, wherein the content of the repeating unit (x) is 90% or more by mole based on all repeating units in the resin (C).
