To provide a manufacturing method and a manufacturing apparatus with which a cast article having less distorsion in the shape with a low pressure can efficiently be manufactured with a low-pressure casting method.

This invention relates to the method and the apparatus for manufacturing the cast article with the low pressure, with which molten metal is filled up into a cavity in a gypsum mold 10 with the low pressure casting method and the casting 2 solidified just after solidifying the molten metal is rectified in such a state as integrated with the gypsum mold 10.
