PROBLEM TO BE SOLVED: To propose a metal-resin integrated molding manufactured by two-color injection molding and exhibiting a favorable electromagnetic shieldability over a broad frequency band. ! SOLUTION: The overall electromagnetic shield characteristic of the provided metal-resin integrated molding 1A is determined by a first electromagnetic shield characteristic ascribed to the metallic material of a metallic molding portion 3, a second electromagnetic shield characteristic ascribed to a first additive 5 mixed with the metallic molding 3 portion, and a third electromagnetic shield characteristic ascribed to a second additive 6 mixed with a resin molding 4 portion. The first and second additives 5 and 6 are mixed respectively with separate molding portions, and since degradations of intrinsic characteristics thereof due to mutual influences can be avoided, an excellent electromagnetic shield characteristic is exhibited over a broad band. !
