A first sleeve 30 regulates the horizontal relative position between an upper mold 10 and a lower mold 20 that are insertable into the first sleeve 30 from its both end sides. A second sleeve 40 provided inside the first sleeve 30 and surrounding the outer periphery of a molding surface 21 of the lower mold 20 supports at least part of an outer peripheral portion of a molding material 50 placed on the molding surface 21 of the lower mold 20 , thereby preventing position offset and slip-off of the molding material 50 . In this state, the molding material 50 is press-molded between the upper mold 10 and the lower mold 20.
