Relieve irritation to the skin of the water vapor which is generated from the heating body to be used against the skin. Heating body 1 comprises a heating element capable of generating steam 31 and a first face sheet 4 is brought into contact with the skin. The first surface sheet 4, to form the base sheet 41 to be transmitted through the water vapor and oxygen, and a short fiber 42 a large number of which projects at a uniform height from the base sheet 41.肌に当てて使用する加温体から発生させた水蒸気の肌に対する刺激をやわらげる。加温体1は、水蒸気を発生可能な発熱体31と、肌に接触させる第1表面シート4とを有する。第1表面シート4は、酸素と水蒸気を透過させる基材シート41と、基材シート41から一様な高さで突出する多数本の短繊維42とで形成する。
