摘要： An object of the present invention is to provide a molten ingot of a platinum group metal or a platinum group-based alloy having a high material yield by suppressing a scattering phenomenon during heating and melting in a method for producing a platinum group metal or a platinum group-based alloy. The method for producing a platinum group metal or a platinum group-based alloy according to the present invention includes a preparing step of weighing a raw material that is partially or entirely of powder and, when the alloy is to be produced, mixing the weighed raw material to obtain a powder mixture, a molding step of molding and solidifying the prepared raw material to obtain molded bodies, a sintering step of sintering the molded bodies to obtain a sintered body, a melting step of melting the sintered body to produce a molten ingot, and a deformation processing step of processing the molten ingot. In the sintering step, the molded bodies are sintered in a stacked state to produce a sintered body as a joined body.
