摘要： A block copolymer composition comprising: a polymer (a) comprising more than 95% by mass and 100% by mass or less of a vinyl aromatic monomer unit and 0% by mass or more and less than 5% by mass of a conjugated diene monomer unit; and a block copolymer (b) comprising 15% by mass or more and 50% by mass or less of a vinyl aromatic monomer unit and 50% by mass or more and 85% by mass or less of a conjugated diene monomer unit, wherein a mass ratio of the polymer (a) to the block copolymer (b) satisfies: (a)/(b)=70/30 to 30/70.
