PROBLEM TO BE SOLVED: To prevent molten metal from spouting from a mating surface in metallic molds, a matching surface of a core and the like only by fastening the metallic mold by an ordinary mold fastening force, even when the metallic mold is not made very precise. SOLUTION: In the low speed and high pressure casting method, by which the molten metal M is filled up in a cavity 2, and then the molten metal M in the cavity is cast at the low speed and the high pressure with a pressurizing element 5, when the molten metal M filled up in the cavity is started to solidify, such casting pressure as not to spout the molten metal from the mating surface in the metallic molds and thereafter, the casting is performed while continuously and linearly making higher of the casting pressure according to the solidification in such degree that the outer peripheral portion of the molten metal in the cavity is not spouted from the mating surface in the metallic molds.
