め、調湿性能は十分ではなかった。[0003] Therefore, it has been proposed to use a so-called wood-based molded product formed by dispersing wood fibers in a resin, as a decorative material for interior use. The wood-based molded body is obtained by, for example, defibrating a wood piece such as a chip with a defibrating machine or the like to form a wood fiber, mixing a thermoplastic resin such as polypropylene with the wood fiber, and compression-molding. Such a wood-based molded article has a humidity control property derived from the wood fiber, but the resin melts at the time of molding, a resin layer is generated on the surface of the molded article, and the resin covers the surface of the wood wet fiber. Therefore, the humidity control performance was not sufficient.

得られる。As described above, the decorative material of the present invention can be manufactured by a simple method of laminating a base material layer, a humidity control material layer, and a skin material layer and hot-press molding. The humidity control material layer is sandwiched between the base material layer and the skin material layer, and is held inside without being peeled off because it is fixed by the thermoplastic resin. Since the skin material layer is porous, the humidity control material provided inside can absorb and release moisture according to a change in humidity in the room where the decorative material is installed.
In addition, if a material having humidity control properties such as wood is used as the skin material layer, the skin material layer can also exert a humidity control function. Further, a deodorant function can be added by adding a deodorant to the humidity control material layer, and an aroma function can be added by adding a fragrance. Further, since both the surface and the inside are porous, a sound absorbing effect can be obtained.
