PURPOSE: To reduce cycle time and to improve yield so as to produce a high quality and sound casting.

CONSTITUTION: In the differential pressure casting device constituted so that a molten metal 40 is filled in a cavity space 10 through a stoke 3, molten metal distributing part 20 and gate 21, a resistance member 5 having passing resistance of molten metal is provided at the position near the cavity space 10 of gate 21. By shortening pressure holding time. The molten metal in a casting plan part 2 is returned to a crucible 4, on the other hand, the molten metal in the cavity space 10 is prevented from passing/falling due to passing resistance in the resistance member 5.
