    • PROBLEM TO BE SOLVED: To provide a resist composition which ensures good resolution of a pattern obtained. SOLUTION: The resist composition comprises: a resin comprising a structural unit derived from a monomer containing a phenolic hydroxyl group; an acid generator represented by formula (I); and at least one compound selected from the group consisting of compounds represented by formula (II) and compounds represented by formula (III), wherein Q 1 and Q 2 represent a fluorine atom or 1-6C perfluoroalkyl; X 1 represents a 1-6C saturated hydrocarbon group, provided that hydrogen atoms contained in the saturated hydrocarbon group may be substituted by hydroxyl groups and that -CH 2 - contained in the saturated hydrocarbon group may be substituted by -O- or -CO-; Z + represents an organic counter cation; R 1 to R 3 each independently represent 1-6C alkylene; and R 4 to R 7 each independently represent 1-6C alkyl, provided that hydrogen atoms contained in the alkyl may be substituted by hydroxyl groups.
