(57) [Abstract] [Purpose] To provide a novel far-infrared radiation material capable of efficiently radiating thermal energy required for excitation of water molecules contained in plants and animals including human bodies. [Structure] The far-infrared radiation material of the present invention is alumina 5-6. 0 to 20% by weight, at least one titanium compound selected from titanium dioxide, titanium carbide and titanium boride 20 to 70% by weight, at least one zirconium compound 20 to 50 selected from zirconia, zirconium carbide and zirconium boride. % By weight, and 0.01 to rare earth metal oxides A far-infrared radiation material in the form of a plate, a cylinder, a sheet or a fiber is formed from a composition containing 0.5% by weight and a synthetic resin and used. |
