The present invention pertains to a laminated glass obtained by: interposing, between glass plates, a resin sheet comprising a resin composition obtained by blending 100 parts by weight of a specific modified hydrogenated block-copolymer having an introduced acid anhydride group, and a total of 0.001 to 2.0 parts by weight of a near infrared ray-absorbing pigment and/or a metal oxide particulate having a function of shielding infrared ray, to obtain a laminate; and integrally bonding the laminate including the glass plates and the resin sheet. The aspects of the invention provide a novel hydrogenated block copolymer having an acid anhydride group; a resin composition that includes the hydrogenated block copolymer, has excellent heat insulating function, and is suitable as a laminated glass intermediate film-forming material excellent in moisture resistance and durability; a resin sheet made of the resin composition; and a laminated glass in which the resin sheet is interposed between glass plates through an adhesive and the laminate including the glass plates and the resin sheet is adhesively integrated.
