| 摘要 |
An infrared irradiation source of an infrared irradiation apparatus is provided. The infrared irradiation source is comprised of a heat generator and an infrared ray irradiation member for being heated by the heat generator and emitting far infrared rays not containing near infrared rays of wavelength less than 4 mu m, wherein the heat generation rate by the heat generator is designed to be greater at the circumferential portion than at the central portion of the far infrared irradiation member. Preferably, the infrared irradiation source should be provided in a plurality of numbers so as to emit far infrared rays of wavelength ranging from 5 to 20 mu m to the periphery of the human body accommodated in a space formed by the human body mounting portion and the operable cover portion of the apparatus.
