To provide a composite material panel using a genuine bamboo as a natural material which meets the requirements of a genuine-article oriented user and easily imparts a comfortable and amusing space at a low cost, in view of the present living circumstances in which the opportunities for people to come across living necessities using the natural material are scarce and instead, standardized industrial products based on artificial materials dominate the market.

An adhesive 4 is applied to the back face of a bamboo board material 2 partially molded like an arc-shaped batten and the plane of a heterogeneous board material 3. Then a plurality of the bamboo board material 2 are arranged in parallel on the plane of the heterogeneous board material 3 and are bonded together under pressure. Thus the composite material panel a1 using a bamboo is fabricated by combining both bamboo board material 2 and heterogeneous board material 3 in one piece and can be freely cut in a design art fashion as indicated by a cutting line 5.
