The female mold has a cavity surface for forming a cavity, and a parting surface having an outer peripheral section on which to hold a decorative sheet, and an inner peripheral section extending between the inner edge of the outer peripheral section of the parting surface and the edge of the cavity surface in a concavely curved shape to allow the expansion of a peripheral portion of the decorative sheet around a decorating portion of the same during preforming.
