A far-infrared device includes a flat circular shell, the interior of which is composed of far-infrared releasing substances. The far-infrared releasing substances emit far-infrared rays with a wavelength of 4-14 u03bc m, a emissivity coefficient of more than 0.9, and can continuously generate a static current of 0.06MA, wherein the far-infrared rays with a wavelength of 4-14 u03bc M can be emitted by electromagnetic waves； and the far-infrared releasing substances Its components include 70-95% alumina, 1-20% silica and 1-10% zirconia. The flat circular shell can be made into a patch for sticking on the electric device and the electronic device.一種遠紅外線裝置，包括一扁圓形機殼，其內部由遠紅外線釋放物質所構成，該遠紅外線釋放物質所釋放之遠紅外線在波長4~14微米，其放射係數在0.9以上，並能持續產生0.06mA靜電流，其中波長4~14微米的遠紅外線可藉由電磁波發射出去；及其中該遠紅外線釋放物質的成分包含70~95%之氧化鋁、1~20%之氧化矽及1~10%之氧化鋯。該扁圓形機殼可作成貼片以貼在電氣裝置及電子裝置上。
