[Solution] A block copolymer composition of a vinyl aromatic hydrocarbon and conjugated a diene, wherein the conjugated diene content of the block copolymer component (I) having a molecular weight peak within a molecular weight range of 150,000 to 300,000 and a tapered block is 10 to 20 mass%, the conjugated diene content of the block copolymer component (II) having a molecular weight peak within a molecular weight range of 50,000 140,000 to and tapered block a is 30 to 50 mass%, and the molecular weight peak surface area ratio (I)/(II) of the block copolymer component (I) and block copolymer component (II) in the block copolymer composition is 20/80 to 80/20. 0\ l> 00 (57)®$: [is®] XHE®#, yjxz-rtytma&m&ttizmLtz* mtitz ytR, 5tJS.
