Claim:
A metal-resin composite body comprising: a resin structure having a predetermined shape and including a base resin and a resin structure component; and a metal component integrated with the resin structure, wherein said base resin is integrated with at least a part of a surface of the metal component, where the resin structure is to be integrated, by injection molding, and wherein the separately manufactured resin structure component is joined to the base resin to thereby form the resin structure, characterized in that the base resin has an opening extending therethrough, said opening defining an inner circumferential face, and the separately-manufactured resin structure component has a fitting convex portion and a flange portion, said fitting convex portion having an outer circumferential face and being disposed at an end of the separately-manufactured resin structure component, said flange portion projecting outwardly in an outer circumferential direction from said outer circumferential face of the fitting convex portion, said fitting convex portion of said resin structure being dimensioned to be received within the opening of said base resin without any gap between said outer circumferential face of said fitting convex portion and said inner circumferential face of said opening, and said flange portion of said separately-manufactured resin structure being joined to the base portion.
