A mold and a process which can make such a product without bringing about any substantial change in an ordinary foam-molding operation. A part of foamable resin particles which are fed into the mold for making the product are caused to contact a mold surface heated to or above the melting point of the particles and melt to form a molten resin layer, and the molten resin layer is hardened to form the hardened surface layer.
