分であった。However, in the prior art, although the vibration proof property is ensured, the heat insulating property is inferior. For this reason, as shown in FIG. 3 and FIG. 4, it is considered that a resin sheet made of a soft resin foam is interposed between the base material plywood and the veneer. Bubble 6 'is a substantially perfect circle, deforms greatly upon compression, and has a small shock absorption capacity. In high-foam resin sheet 3 ", bubble 6" is flat near the surface, but the inside is flat. The shape was substantially a perfect circle, and although the deformation due to compression was smaller than that of the resin sheet 3 'made of a low-foamed material, the impact absorbing power was insufficient.

Since a veneer is adhered on top of it and a cushioning material is laminated on the back surface of the base material plywood, it is possible to ensure soundproofing, as well as bubbles in the pressure-formed sheet of soft resin foam particles. Due to the flat shape, the deformation is small with respect to the compression, the shock absorbing ability is increased, the surface strength is increased, and the heat insulating property is ensured.
