Abstract
A partially hydrogenated block copolymer of the present invention includes: a polymer block (A) containing a vinyl aromatic monomer unit as a main component: and a polymer block (B) containing a conjugated diene monomer unit, wherein in a differential molecular weight distribution (B) of a degradation product of the partially hydrogenated block copolymer obtained by an ozone degradation method, a distribution of degree of hydrogenation H, which is given by a maximum peak height in a region of a molecular weight of 800 or more and 3,000 or less, is 0.01 to 0.5.
