A lower mold has a bottom surface member and a side surface member. An upper end surface of the bottom surface member forms an inner bottom surface of a cavity and has a planar shape corresponding to an unusual planar shape of a sealing resin. A substrate is disposed on a mold surface of an upper mold such that a component to be sealed attached to the substrate faces downward, and the cavity is filled with a fluid resin. The upper mold and the lower mold are clamped, and the component is immersed in the fluid resin. The bottom surface member is raised, and the fluid resin is pressed at a prescribed resin pressure and cured to form the sealing resin. The bottom surface member and the side surface member are moved relatively, and thereby, a molded product is released from a mold surface of the lower mold.
