PROBLEM TO BE SOLVED: To provide a method for stably producing a parent mixed metal for an accessory, which has an effect of emitting far-infrared rays and can be variously formed into the accessory. SOLUTION: The method for producing the parent mixed metal containing ceramic for the healthy accessory comprises: a ceramic-powder-charging step of charging 0.2 to 0.25 (wt.%) ceramic powder mainly made of silicon oxide with respect to the base metal, into the bottom of a crucible; a base-metal-charging step of charging the base metal of a noble metal onto the ceramic powder inside the crucible; a heating and melting step of heating the crucible having the ceramic powder and the base metal charged therein, to a melting temperature of the base metal in a high-frequency furnace to produce a molten material; a molding step of casting the molten material into a mold having a lower temperature than the heating temperature and leaving it; and a cooling step of naturally cooling a molded article taken out from the mold and then quenching it.
