ABSTRACT:
A polyolefin resin drawn sheet4is laminated on at least one face of a sheet-form core material6having a density of 30 to 300 kgf/m3. At this time, a sheet or film5made of a bonding synthetic resin or rubber having a flow starting temperature lower than the thermal deformation temperature of the core material6and the melting point of the drawn sheet4is interposed between the core material6and the drawn sheet4. The resultant stack product is heated to not less than the flow starting temperature of the synthetic resin or the rubber and not more than the thermal deformation temperature of the core material6and the melting point of the drawn sheet4. At the same time of or after the heating, the stack product is pressed to apply a compression strain of 0.01 to 10% to the core material6.
