PROBLEM TO BE SOLVED: To provide a production method for a metallic complex product with which the desired portion and range in the metallic injection-formed product can be strengthened by filling reinforcing materials. SOLUTION: When the metallic complex product which disperses the reinforcing materials in a base metal, is produced with the injection-forming method, preforms formed in advance from the reinforcing material, are beforehand arranged to the desired positions in a cavity of metallic mold, and the molten base metal is injected into the cavity and filled and impregnated into the preforms of the reinforcing material. The portion can particularly be reinforced only disposing the preforms to the desired positions in the cavity. The preform can be dispersed at any position in the cavity by adopting the suitable design with a projection for engaging and an overflow part while allowing the preform of the reinforcing material to have the projections for engaging at this surroundings and to be disposed in the cavity by engaging these projections with the overflow part communicated with the cavity in the metallic mold, and the product can sufficiently be reinforced at the desired portions.
