摘要：
A modified hydrogenated diene polymer composition includes (A) a modified hydrogenated diene polymer obtained by hydrogenating a diene polymer having a vinyl bond content of 20 to 70%, the modified hydrogenated diene polymer having a weight average molecular weight (Mw) of 100,000 to 1,700,000, a molecular weight distribution (Mw/Mn) of 1.0 to 3.0, and a hydrogenation rate of 72 to 96%, and containing a functional group, and (B) a diene rubber, the modified hydrogenated diene polymer composition containing the modified hydrogenated diene polymer (A) and the diene rubber (B) in an amount of 100 parts by mass in total, the amount of the modified hydrogenated diene polymer (A) being 60 to 95 parts by mass, and the amount of the diene rubber (B) being 5 to 40 parts by mass.
