Provided is a polymer compound that has excellent sensitivity, high resolution, and small line edge roughness and is capable of forming a fine pattern precisely, and less causes post-develop defects.
The polymer compound according to the present invention includes a monomer unit (a) and a monomer unit (b). The monomer unit (a) is represented by Formula (a), and the monomer unit (b) includes an alicyclic skeleton containing a polar group. The polar group of the monomer unit (b) is preferably at least one group selected from —O—, —C(═O)—, —C(═O)—O—, —O—, —C(═O)—O—, —C(═O)—O—, —C(═O)—, —C(═O)—NH—, —S(═O)—O—, —S(═O)
