Provided is a polymer including a constituent unit (1) based on a monomer represented by Formula (1), in which a content of a constituent unit based on a monomer having a polycyclic structure is 35 mol % or less. In Formula (1), R 1 represents a hydrogen atom or a methyl group, A 1 represents a linking group including an ester bond, or a single bond, where A 1 has no tertiary carbon atom, and Z 1 represents an atomic group forming a sulfur-containing cyclic hydrocarbon group having 3 to 6 carbon atoms, which includes a carbon atom bonded to A 1 , and —SO 2 —. |
