Claim 0:
1. A polymer composition, comprising:
(A) a conjugated diene rubber wherein a polymer corresponding to the following component (B) is excluded; and
(B) a hydrogenated product of the polymer that satisfies the following (1) to (3), which is the polymer in which 80% or more of structural units derived from butadiene are hydrogenated:
(1) being a copolymer of a conjugated diene compound containing butadiene and an aromatic vinyl compound,
(2) comprising a polybutadiene block having a vinyl group content of 20% or less, and
(3) comprising a block composed of a conjugated diene compound and an aromatic vinyl compound,
wherein, when constituent proportions of a structural unit represented by the following Formula (1), a structural unit represented by the following Formula (2), a structural unit represented by the following Formula (3), and a structural unit represented by the following Formula (4) are set as p, q, r, and s, respectively, the component (B) is a hydrogenated conjugated diene polymer that satisfies the following Formula (A):

0.80≤(p+(0.5×r))/(p+q+(0.5×r)+s)≤0.98  (A),
