Problem to be Solved: A third invention provides a human body cooling apparatus which suppresses uneven distribution due to the migratability of a built-in cooling medium, thereby exhibiting a sufficient cooling effect for the body. Solution: The human body cooling apparatus (301) pertaining to the third invention includes an exterior element (302) in which two covering members in the shape of a rectangular seat each having a front cloth formed of a material selected from cotton fiber, polyester, rayon, hemp, raised fabric, crepe, striped crepe, towel fabric, and the like, and a backing cloth formed of a non-water absorbent material, such as polyvinyl chloride, or the like, which is weldable by high-frequency heating are put one upon another to provide a flat form, said backing cloths being superposed on each other and the backing cloths being high-frequency welded for formation of an outer edge crimped portion (306), a toric partially crimped portion (307) having an air bleeder hole 308 for heat radiation in a plurality of places in an internal area thereof, and straight-linear middle crimped portions (309) and a cooling medium (305) containing gel, sodium polyacrylate, ammonium sulfate, sodium sulfate, glycerin, water, fungicide, and the like, accommodated in said exterior element (302) such that migration thereof is restricted by said outer edge crimped portion (306), partially crimped portions (307) in the internal area thereof, and middle crimped portions (309) said exterior element (302) being capable of reversible use by front/back reversing it.
