The present invention provides a resin composition used for insert molding, a metal resin composite molding body using the resin composition, and a manufacturing method of the metal resin composite molding body. The resin composition used for insert molding can realize the metal resin composite molding body in which joint strength between an insert metal member and a resin member is strong, and can realize excellent impact resistance and low dielectric property (low dielectric constant and low dielectric loss angle tangent), and further realizes high whiteness. The present invention provides a resin composition used for performing insert molding for an insert metal member on which physical treatment and/or chemical treatment are implemented. The resin composition contains 100 parts by mass of (A) polyarylene sulfide resin, 3-55 parts by mass of (B) olefine copolymer containing an epoxy group, and 5-60 parts by mass of (C) polystyrene resin, wherein the ratio ((B)/(C)) between the content of the (B) olefine co
