Zusammenfassung:	There is provided a block copolymer A which is represented by a following general formula (I), wherein a ratio ((Ar1-D1)/D2) of a mass of a branched chain represented by Ar1-D1 to a mass of a branched chain represented by D2 is 1.0/0.15 to 1.0/1.75, (Ar1-D1)mX(D2)n (I)where, in the formula (I), Ar1-D1 and D2 are each a branched chain bonded to X, Ar1 is an aromatic monovinyl polymer block, D1 and D2 are each a conjugated diene polymer block, "m" is an integer of 1 or more, "n" is an integer of 1 or more, "m"+"n" is an integer of 3 or more, and X is a residue of a polyfunctional coupling agent.
