Claim Text:
1. A resist composition comprising: a base component (A), which exhibits changed solubility in a developing solution under action of acid, comprising a resin component (A1) having a structural unit (a2 wherein R α represents a hydrogen atom, a methyl group or a trifluoromethyl group, wherein the structural unit (a2 wherein R represents a hydrogen atom, an alkyl group of 1 to 5 carbon atoms or a halogenated alkyl group of 1 to 5 carbon atoms, R an acid generator component (B), which generates acid upon exposure, comprising an acid generator (B1) containing a compound represented by general formula (b1-1-0) shown below wherein g represents an integer of 1 to 4; and each of R 1 ″ to R 3 ″ independently represents an aryl group, provided that at least one of R 1 ″ to R 3 ″ has —O—C(═O)—R 7 ′ as a substituent, wherein R 7 ′ represents a linear or branched saturated hydrocarbon group of 1 to 25 atoms, a cyclic saturated hydrocarbon group of 3 to 20 carbon atoms, or a linear or branched aliphatic unsaturated hydrocarbon group of 2 to 5 carbon atoms; and a nitrogen-containing organic compound component (D), the nitrogen-containing organic compound component (D) comprising a compound (D1) represented by general formula (d1) shown below: wherein R 60 a group in which one or more hydrogen atoms have been removed from a polycycloalkane, Y 1 represents a divalent linear, branched or cyclic aliphatic hydrocarbon group, R 61 represents a hydrogen atom, fluorine atom, alkyl group or fluorinated alkyl group, q represents an integer of 1 to 10, and A + represents an organic cation.
