Is the water-permeable packaging material 4 on the side of the bag 2 that is in contact with the human body, and the water-impermeable packaging material 5 is the side of the bag 2 that is not in contact with the human body. In the bag 2, the water-permeable packaging material 4 and the water-impermeable packaging material 5 are contacted face-to-face and sewn in a tuft at appropriate intervals to form a plurality of pouches 2a in a series.

The water-permeable packaging material 4 is a cloth in a specific example, and is water-infiltrating. Since the size of the particles of the super absorbent polymer 3 is about 10 times the size of the cloth, the super absorbent resin 3 does not leak from the water permeable packaging material 4. In the specific example, the water-impermeable packaging material 5 is a cloth that is waterproof, and is impermeable to water and steam. The water-vapor and superabsorbent resin 3 are water-impermeable packaging material 5. Do not leak from.

The heat storage material 9 is the superabsorbent resin 3, and the superabsorbent resin 3 is the released superabsorbent resin 6. The highly absorbent water-releasing resin 6 is a granular material having water absorbability, has a water absorbing power, and exhibits a heat storage effect. Specifically, the highly water-absorbent resin 3 absorbs several hundred times its own weight of water in a short time, and when it absorbs water, it becomes a stable gel, does not become sticky, and has a moisture releasing property. The discharged superabsorbent resin 6 is filled in the pouch 2a.
