Claim Text:
1. A resist composition comprising: a base component (A) that exhibits increased solubility in an alkali developing solution by the action of acid; a photo-base generator component (C) that generates a base upon; and an acidic compound component (G), the photo-base generator component (C) comprising a compound represented by general formula (C1-1-1) shown below: wherein each of R 1 and R 2 independently represents a hydrogen atom, an alkyl group which may have a substituent, or a phenyl group which may have a substituent, provided that at least one of R 1 and R 2 represents an alkyl group or a phenyl group, and R 1 and R 2 may be mutually bonded to form a ring together with the nitrogen atom in the formula, and wherein the acidic compound component (G) comprises an acidic salt (G1) or an acid other than the acidic salt (G2), wherein the acidic salt (G1) is an ionic compound consisting of a nitrogen-containing cation moiety represented by any one of general formulas (G1c-11) to (G1c-13) shown below and at least one counteranion selected from the group consisting of counteranions represented by formulae (b1) to (b9) and (G1a-3) shown below, and wherein the acid other than the acidic salt (G2) is an acid component represented by formula (G2-31) shown below; wherein Rf g1 represents a fluorinated alkyl group of 1 to 12 carbon atoms; each of Rn g1 and R g2 independently represents a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, and Rn g1 and R g2 may be mutually bonded to form a ring; each of Q a to Q c independently represents a carbon atom or a nitrogen atom; Rn g3 represents a hydrogen atom; each of Rn g4 and Rn g5 independently represents an aromatic hydrocarbon group or an alkyl group of 1 to 5 carbon atoms; each of R g1 and R g2 independently represents a hydrocarbon group; each of n15 and n16 represents an integer of 0 to 4; when n15 and n16 represents an integer of 2 or more, a plurality of R g1 and R g2 with which the hydrogen atoms on the adjacent carbon atom have been substituted may be mutually bonded to form a ring; wherein each of q1 and q2 independently represents an integer of 1 to 5; q3 represents an integer of 1 to 12; t3 represents an integer of 1 to 3; each of r1 and r2 independently represents an integer of 0 to 3; g represents an integer of 1 to 20; R 7 represents a substituent; each of n1 to n6 independently represents 0 or 1; each of v0 to v6 independently represents an integer of 0 to 3; each of w1 to w6 independently represents an integer of 0 to 3; and Q″ is the same as defined above; and wherein, X″ represents an alkylene group of 2 to 6 carbon atoms in which at least one hydrogen atom has been substituted with a fluorine atom; and
