摘要：
A modified block copolymer according to the present invention is a modified block copolymer comprising a polymer block comprising a vinyl aromatic compound as a main constituent (A), a polymer block comprising a conjugate diene compound as a main constituent (B), and an atomic group having NHx (x=0 to 2) (C). In the modified block copolymer, the polymer block comprising a conjugate diene compound as a main constituent (B) is a hydrogenated product, the atomic group having NHx (x=0 to 2) (C) is contained in a side chain, and a compound forming the atomic group having NHx (x=0 to 2) (C).
