PROBLEM TO BE SOLVED : To provide a multifunctional indoor building material emitting negative ions and increasing antibacterial and deodorizing actions by using far infrared rays radiated at the same time and by a photocatalyst function material. SOLUTION : This indoor building material is constituted by applying a resin composition to a part or the whole surface, by mixing the photocatalyst function material with a composition including any one of mineral including a high molecular compound and rare earth elements hardly electrified by static electricity and tourmaline or far infrared radiation ceramics in a woody material. Thus, the effect capable of increasing and improving the antibacterial and deodorizing action is performed by the photocatalyst function material, by using the far infrared radiation for emitting-increasing and radiating the negative ion.
