To obtain a uniform quality and uniform cast product by pouring molten metal into a metallic mold with high accurate quantitative regulated pressure and regulated temperature.

In a casting method by feeding the molten metal into the mold through a feeding device inserted into a holding furnace, when the molten metal is force-fed by force-feeding inert gas into the inside upper part of a feeding vessel in the feeding device, the molten metal surface at the starting time of force-feeding is held to the constant and the molten metal is fed while using the molten metal pressure with the pre-set pressure pattern.
