The concave design forming unit with the desired form is formed on the surface of the molded component easily in the case of injection molding by using the low melting point metal material. According to this invention, in the injection molding method of low melting point metal material for injecting the molten metal formed of low melting point metal material into the injection molding cavity of the predetermined shape provided in the metal mold, and after mold curing said molten metal, taking out the molded goods from the injection molding cavity; the injection molding cavity will be formed inside by the first metal mold unit and the second metal mold unit contacted and the metal mold having the trapezoidal concave design forming unit with the predetermined height formed on the metal mold inside surface of the first metal mold unit or the second metal mold unit forming said injection molding cavity will be heated to the prescribed metal mold temperature, and the molten metal heated to the predetermined molten temperature will be injected into the injection molding cavity of said heated metal mold at the predetermined injection rate, and after said molten metal injected is being chilled and solidified, separated into the first metal mold unit and the second metal mold unit and the molded component will be taken out from the injection molding cavity.
