Provided is a resin composition with which it is possible to obtain a resin molded article having excellent heat dissipation properties. The present invention relates to a resin composition containing a thermoplastic resin, graphite, and a fiber body, and when a resin molded article (1) having a length of 100 mm * a width of 100 mm * a thickness of 2 mm is obtained by filling a molten resin composition into a mold from a direction orthogonal to the thickness direction of the resin molded article (1) to be obtained and molding the resin composition, the resin molded article (1) having a length of 100 mm * a width of 100 mm * a thickness of 2 mm is obtained. In a cross-section obtained by cutting the resin molded body (1) in a direction (X) parallel to the filling direction and in the thickness direction (Z), the average orientation angle (A) of graphite with respect to the plane direction in at least one of the outermost layer-side regions (1A) and (1E) among the regions (1A)-(1E) equally divided in the thickn
