A polymer composition includes a polymer (A) having, when composition ratios (molar ratios) of a structural unit represented by formula (1), a structural unit represented by formula (2), a structural unit represented by formula (3), and a structural unit represented by formula (4) in the polymer (A) are p, q, r, and s, respectively, a value α represented by formula (i) of 0.60 or more:with a weight average molecular weight (Mw) of 1.0×105 to 2.0×106 in terms of polystyrene measured by gel permeation chromatography, and a carbon-carbon unsaturated bond; and a paraffin wax (B) having a melting point of 70° C. or more.
