Zusammenfassung:	To provide a manufacturing method of a metal molding capable of suppressing oozing out, from a metallic component, of molten liquid which may be generated by a heat treatment of the metallic component.SOLUTION: A manufacturing method of a metal molding includes a preparation step for preparing a metallic component, an application step for applying a ceramic coating on the metallic component, and a heat treatment step for heat-treating the metallic component on which the ceramic coating is applied. Assuming that a solid phase line temperature of a composition of the metallic component is Ts[°C], the temperature T1[°C] in the heat treatment step satisfies inequalities (Ts-70)≤T1≤Ts+30.SELECTED DRAWING: Figure 1 【課題】金属部材の熱処理によって生じ得る溶融液が金属部材から浸み出すのを抑制できる金属成形品の製造方法の提供。【解決手段】金属成型品の製造方法は、金属部材を準備する準備ステップと、金属部材にセラミックコーティングを塗布する塗布ステップと、セラミックコーティングが塗布された金属部材を熱処理する熱処理ステップとを含む。熱処理ステップの温度Ｔ１［℃］は、前記金属部材の組成の固相線温度をＴｓ［℃］とすると、（Ｔｓ−７０）≦Ｔ１≦Ｔｓ＋３０である。【選択図】図１
