Claim:
1. A resist composition which generates acid upon exposure and exhibits changed solubility in a developing solution under action of acid, the resist composition comprising: an organic compound component (A) which exhibits changed solubility in a developing solution under action of acid; and an acid-generator component (B) comprising a compound (B0-1) represented by general formula (b0) shown below: wherein Ra 1 represents an aromatic ring; Ra 01 represents a linear alkyl group of 10 or more carbon atoms; Ra 02 and Ra 03 each independently represents an alkyl group of 1 to 10 carbon atoms optionally having a substituent; n1 represents an integer of 1 to 5; n2 represents an integer of 0 to 2; n3 represents an integer of 0 to 4; and X − represents an anion represented by any one of general formulae (b-1) to (b-3) shown below: wherein R 101 and R 104 to R 108 each independently represents a cyclic group optionally having a substituent, a linear or branched alkyl group optionally having have a substituent or a linear or branched alkenyl group optionally having a substituent, provided that R 104 and R 105 may be mutually bonded to form a ring; R 106 and R 107 may be mutually bonded to form a ring; R 102 represents a fluorine atom or a fluorinated alkyl group of 1 to 5 carbon atoms; Y 101 represents a single bond or a divalent linking group containing an oxygen atom; V 101 to V 103 each independently represents a single bond, an alkylene group or a fluorinated alkylene group; L 101 and L 102 each independently represents a single bond or an oxygen atom; and L 103 to L 105 each independently represents a single bond, —CO—or —SO 2 —.
