  A resist composition that contains a base material component exhibiting changed solubility in a developing solution under action of acid and a compound (D0) represented by General Formula (d0), in which R 01 , R 02 , R 03 , and R 04 each independently represents a hydrogen atom, a hydroxy group, a halogen atom, or an alkyl group; alternatively, R 01 and R 02 , R 02 and R 03 , or R 03 and R 04 are bonded to each other to form an aromatic ring; R 05 represents a hydrogen atom or an alkyl group; Y represents a group that forms an alicyclic group together with a carbon atom *C; provided that at least one of the carbon atoms that form the alicyclic group is substituted with an ether bond, a thioether bond, a carbonyl group, a sulfinyl group, or a sulfonyl group; m represents an integer of 1 or more, and M m+ represents an m-valent organic cation
