Abstract

In order to prevent positional displacement of a graphite sheet laminate during production of a resin molded product obtained by integrally molding the graphite sheet laminate and a resin, the present invention uses a graphite sheet laminate having a structure in which a first fixing layer having a modulus of elasticity of not less than 7.0×10Pa and not more than 5.0×10Pa at 250° C. is in contact with a graphite sheet on at least one of principal surfaces of the graphite sheet.
