A high-melting-point molten metal is cast into the low-melting-point metal part to form a welded joint between the high-melting-point metal part and the low-melting-point metal part, and the mechanical strength peculiar to the cast metal is also secured, resulting in a higher joining strength than before. As a result of research to obtain a composite of a melting point metal portion and a low melting point metal portion, as shown in FIG. 1 (a), a low melting point metal portion 5 having an inverse tapered groove or a bottom spreading hole 7 is used as a mold. When the molten metal having a high melting point is cast so as to be in contact with the molten metal, the surface of the low melting point metal part 5 is melted to form a welded joint 6 between the high melting point metal part 2 and the low melting point metal part 5, and vice versa. From the fact that the shape of the taper groove or the bottom spreading hole 7 is not significantly deformed, it has been found that the mechanical coupling strength can be secured.
