摘要：
A main object of the present invention is to provide a block copolymer composition which has good elasticity, while having excellent stress relaxation properties. The object is achieved by providing a block copolymer composition obtained by a modification treatment, the block copolymer composition comprising a block copolymer B formed by introducing a functional group capable of forming a non-covalent bond into a block copolymer A including at least one aromatic vinyl polymer block and at least one conjugated diene polymer block.
