To provide a human body cooling and heating device that can prevent temperature saturation of a Peltier element, and achieve simplification and weight reduction of the device.SOLUTION: A human body cooling and heating device 1 includes a tube body 3 having a surface 31 opposed to the skin of a human body 2, air supply means 7 for feeding pressurized air into the tube body, Peltier elements 5, 5, ... subjecting the pressurized air inside the tube body to heat treatment, and a power supply part 9 for supplying power to Peltier elements and the air supply means. The tube body is bored with a plurality of air blowout holes 32, 32, ... on the surface opposed to a skin surface 21 of the human body. The diameter of the air blowout holes becomes larger as a distance from an air introduction part 33 increases.SELECTED DRAWING: Figure 2【課題】ペルチェ素子の温度飽和を防止し、かつ装置の簡素化・軽量化を図った人体冷暖房装置を提供する。【解決手段】人体冷暖房装置１は、人体２の皮膚に対向する面３１を有するチューブ体３と、チューブ体内に圧力空気を送り込む空気供給手段７と、チューブ体内部の圧力空気を熱処理するペルチェ素子５，５，…と、ペルチェ素子と空気供給手段に電力を供給する電源部９とを備え、チューブ体には人体の皮膚面２１に対向する面に複数の空気吹出し孔３２，３２，…が穿設されていて、空気吹出し孔の孔径が空気導入部３３から遠ざかるに従って大きく穿設されたものである。【選択図】図２
