The partially hydrogenated block copolymer of the present invention has a polymer block (A) mainly composed of a vinyl aromatic monomer unit and a polymer block (B) containing a conjugated diene monomer unit, and In the differential molecular weight distribution (B) of the decomposition product of the partially hydrogenated block copolymer obtained by the ozonolysis method, when the maximum peak height in the region of the molecular weight of 800 or more and the molecular weight of 3,000 or less is the hydrogenation rate distribution H, The H is 0.01 to 0.5. |
