Abstract:
1. An actinic ray-sensitive or radiation-sensitive resin composition, comprising: (A) a resin capable of increasing the solubility of the resin (A) in an alkali developer by the action of an acid; and (B) a compound capable of generating an acid upon irradiation with an actinic ray or radiation, wherein: (B) the compound capable of generating an acid upon irradiation with an actinic ray or radiation is contained in an amount of 10.6 to 18.4 mass % based on the entire solids content of the actinic ray-sensitive or radiation-sensitive resin composition, and the actinic ray-sensitive or radiation-sensitive resin composition contains at least one of the compounds represented by formulae (1-1) and (1-2) as the compound (B): wherein in formula (1-1), R R each R l represents an integer of 0 to 2; r represents an integer of 0 to 8; and X and in formula (1-2), M represents an alkyl group, a cycloalkyl group, an aryl group or a benzyl group and when M has a ring structure, the ring structure may contain an oxygen atom, a sulfur atom, an ester bond, an amide bond or a carbon-carbon double bond; each of R each of R R X
