< Topic >As an ideal material it is possible, to emit the growth light ray (far infrared line wire) which quite is close to the blackbody it permeates to the system which is deeper than superficial temperature of the human body, activates the cell of the body core part, it offers the growth light ray thermal vessel where effect such as expansion of minute vascular and promotion of blood wraparound is expected.SolutionsPlate-like heat transfer body 3 of cube or the rectangular parallelepiped to 0.5 distributing solidifying the graphite silica which - 100.0mm to piece is converted to thermosetting metaplasia elastomer, being something which was formed, Fe to be abbreviated and removed from the graphite silica, heating element 5 contacts the base of the plate-like heat transfer body, generates the far infrared line wire wavelength of 4 - 14 millimicrons than plane surface of the plate-like heat transfer body the heating element in surface temperature by emitting heat 40 - the 50. Distribution facilities heat insulation material 8 it is desirable under the heating element to do.< Choice figure >Drawing 3【課題】理想物質としての黒体に極めて近い生育光線(遠赤外線)を放射することができ、人体の表在温度よりも深い組織に浸透し、体芯部の細胞を活性化させ、微細血管の拡張、血液循環の促進などの効能が期待される生育光線温熱器を提供する。【解決手段】立方体又は直方体の平板状伝熱体3が0.5~100.0mmに個片化されたグラファイトシリカを熱硬化性エラストマーに分散固化して形成されたものであって、グラファイトシリカからはFeが略除去されており、平板状伝熱体の底面には発熱体5が接触しており、発熱体を表面温度40~50℃に発熱させることによって、平板状伝熱体の平面より4~14μmの遠赤外線波長を発生する。発熱体の下に断熱材8を配設するのが好ましい。【選択図】図3
