摘要：
A hydrogenated copolymer comprising a copolymer block A comprising a vinyl aromatic compound monomer unit and a conjugated diene monomer unit, wherein a tan δ peak obtained by dynamic viscoelasticity measurement (1 Hz) is in the range of −40° C. to 20° C., a value of the tan δ peak is 0.8 or more, and a half value width of the tan δ peak is 22° C. or less.
