PROBLEM TO BE SOLVED: To provide a hydrogenated styrene based elastomer laminate for bonding diene based rubber which is excellent in bondability with diene based rubber and dynamic physical properties. SOLUTION: This hydrogenated styrene based elastomer laminate for bonding the diene based rubber has a hydrogenated styrene based elastomer layer, and a bonding layer. In this case, the hydrogenated styrene based elastomer layer consists of a block copolymer (A). The block copolymer (A) has at least one of a polymer block (i) consisting of a conjugated diene compound unit and two or more of polymer blocks (ii) consisting of a vinyl aromatic compound unit, and 90 mol% or higher of a carbon-carbon unsaturated double bond included in the polymer block (i) is hydrogenated. The bonding layer consists of a conjugated diene based copolymer which is selected from a block copolymer (B) having a conjugated diene based copolymer block at a part of the polymer main chain, and a graft copolymer (C) of which the whole of the polymer main chain is substantially the conjugated diene based polymer.
