PURPOSE: To integrate a sintered body and a casting by mounting materials for sintering to a wax patterns to form the cavity of a casting mold and casting the materials by a lost wax method.

CONSTITUTION: The materials for sintering essentially consisting of the noble metals are mounted at ≥1 points of the wax pattern and are sintered at the m.p. of the material for sintering or below and are then cast by the lost wax method at the time of producing the noble metal ornaments. The resulted ornaments are eventually integrated with the sintered body and the casting. The casting having the surface constituting a smooth specular surface and the sintered body having a satin surface are thus combined, by which the ornaments having the extremely aesthetic value are obtd.
