The following resist composition which is excellent particularly in transparency to light beams and dry etching properties and gives a resist pattern excellent in sensitivity, resolution, evenness, heat resistance, etc., as a chemical amplification type resist, is presented. A resist composition which comprises a fluoropolymer (A) having repeating units represented by a structure formed by the cyclopolymerization of one molecule of a fluorinated diene and one molecule of a monoene, in which the monoene unit in each repeating unit has a blocked acid group capable of regenerating the acid group by the action of an acid, an acid-generating compound (B) which generates an acid upon irradiation with light, and an organic solvent (C).
