PROBLEM TO BE SOLVED: To provide a manufacturing method of a metallic composite formed body, by which trouble in the boundary surfaces of plural formed bodies composed of different kinds of materials or a same kind of material can be restrained, and an injection-forming mold. SOLUTION: This manufacturing method of the metallic composite formed body is the method in which, after injection-forming a first formed body 11 with a metallic powder injection-forming method for injection-forming a forming material obtained by mixing the metallic powder and a binder into the mold, a second formed body 12 is injection-formed in the state closely stuck to the first formed body 11 to integrate both the formed bodies. In the first formed body 11, a joining surface 110 low in the binder concentration, is formed and the second formed body 12 is injection-formed so as to be brought into contact with the joining surface 110.
