Abstract: It is an object of the present invention to provide a water-absorbent pad that is made of impermeable cloth or sheet, that is capable of absorbing water when needed and that effectively cools and heats a human face, neck, head and the like. A cooling/heating water-absorbent pad, wherein a water-absorbent sheet made of a material containing water-absorbent polymer is inserted in a planate bag made of impermeable cloth having a closed periphery; the impermeable cloth and the water-absorbent sheet are stitched together such that the impermeable cloth and the water-absorbent sheet are divided into a plurality of areas in a planar view; and water is absorbed into the water-absorbent sheet through a channel formed at the stitched portion. In this moment, water is absorbed into the water-absorbent sheet only via holes made by the stitching and by a capillary action of a thread piercing through the water-absorbent sheet.
