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).

摘要： The present invention provides a resin composition, containing: a component (I) of a modified block copolymer (I) that has a polymer block (A) mainly comprising a vinyl aromatic compound unit, and a polymer block (B) mainly comprising a conjugated diene compound unit, and has 0.01% by mass or more of a polar group; and a component (II) of a resin (II) having a polar group (excluding the component (I)), in which a mass ratio between the component (I) and the component (II), (I)/(II), is 1/99 to 70/30, and the component (I) satisfies the following conditions (i) to (iii):



A content of the vinyl aromatic compound unit in the modified block copolymer (I) is 1 to 30% by mass.
A vinyl bond content is 1 to 55%.
A hydrogenation rate is 5 to 55%.
