Patent ID: 8778595

Claim:
A resist composition, comprising a base component (A) which generates acid upon exposure, and exhibits changed solubility in a developing solution under action of acid, wherein the base component (A) comprises a polymeric compound (A1) having a structural unit (a5) represented by general formula (a5-0) shown below and a structural unit (a6) that generates acid upon exposure: wherein R represents a hydrogen atom, an alkyl group of 1 to 5 carbon atoms or a halogenated alkyl group of 1 to 5 carbon atoms, R 1 represents a sulfur atom or an oxygen atom, R 2 represents a single bond or a divalent linking group, and Y represents an aliphatic polycyclic group in which a carbon atom or a hydrogen atom may be substituted with a substituent, or an aromatic hydrocarbon group in which a carbon atom or a hydrogen atom may be substituted with a substituent.
