A sprue for a low-pressure casting device includes a stalk connection part to be connected to a stalk, a molten metal reservoir and a cavity connection part to be connected to the cavity. The shape of the molten metal reservoir is such that the perimeter of the cross section perpendicular to the flow direction of molten metal gradually increases toward the cavity connection part while the area of the cross section remains constant.
