PROBLEM TO BE SOLVED: To provide a resist composition from which a resist pattern with excellent line edge roughness can be produced.SOLUTION: The resist composition comprises a resin including a structural unit having an acid labile group, a compound expressed by formula (I), and an acid generator expressed by formula (II). In the formulae, Rand Reach represent a hydrocarbon group, alkoxy group, acyl group, acyloxy group, alkoxycarbonyl group, nitro group or halogen atom; m' and n' each represent an integer of 0 to 4; Xrepresents an alkanediyl group optionally having a substituent, in which a methylene group included in the alkanediyl group may be replaced by an oxygen atom or a carbonyl group; Rrepresents a hydrocarbon group optionally having a substituent, in which a methylene group included in the hydrocarbon group may be replaced by an oxygen atom or a carbonyl group; and Zrepresents an organic cation. |
