を得ることができる。As described above, according to the first aspect of the present invention, the surface decorative material is laminated on the surface side of the base material having the cushioning property via the wood powder resin composite material having rigidity. Therefore, by using a base material having cushioning properties,
The overall spring constant per unit area of the base material itself has been reduced, eliminating the need for grooved processing and the attachment of cushioning material to the plywood base material as in the past. Since there is no need to reduce the constant or bending rigidity, it has a simple structure, and by combining a cushioning base material and wood powder resin composite material, it is possible to obtain excellent soundproofing performance, The feeling of walking can be improved. In addition, since wood powder resin composites have higher dimensional stability against temperature and humidity than plywood, etc., surface upholstery materials are pushed up by moisture absorption as in the past, gaps due to drying, cracks on surface upholstery materials are generated. In addition, load resistance can be secured by using wood powder resin composite material on the surface layer of the base material, for example, use of furniture with casters and occurrence of scratches or dents due to impact such as dropping of objects. The problem of occurring also disappears. In addition, the wood powder resin composite material increases the hardness of the entire surface of the panel and provides a smooth surface, so for example the use of furniture with casters or the occurrence of scratches or dents due to the impact of falling objects, etc. In addition, it is possible to obtain a soundproof flooring material that is less likely to cause difficulty and that stockings in a makeup groove and catching of socks do not easily occur.

フォームも容易となる。 Further , the wood powder resin composite material is provided with a real portion arranged on a side surface portion of the floor material to connect adjacent floor materials, and a base material having cushioning property is arranged below the real portion. Since the wood powder resin composite material is provided with the real part, the total spring constant per unit area of the base material itself can be reduced even in the real part, and the soundproof performance can be secured. Furthermore
Is a wood powder resin composite that has a fitting part and a real part on the top surface of the base material.
The fitting part is removably fitted on the lower surface of the composite material.
A base material having cushioning properties because a fitting part is provided
And a wood powder resin composite material having a real part are so-called nested structures.
Easy to align wood powder resin composite during construction
This makes it easier to install and improves the wood powder resin composite material.
Form becomes easy.
