PURPOSE: To use far infrared rays without damaging effects thereof, by making far infrared rays emitted from a ceramic to radiate for infrared rays at normal temperature, through cloth, paper or plastic specifically colored.

CONSTITUTION: Far infrared rays are radiated from powder of far infrared ray radiating ceramic which radiates a large amount of far infrared rays having 8W14μ peak wavelength at normal temperature, through cloth, paper or plastic colored in monochrome of white, green, brown, dark gray or blue or in color obtained by combining the four colors. Consequently, the ceramic is made into fine powder, added to a raw material to make paper, sandwiched in between paper, a plastic may be used instead of the paper or powder of the ceramic is blended with an adhesive and applied to the back of a cloth.
