ABSTRACT:
A disposable body warmer in which a heat-generating agent which oxidizes and generates heat by the presence of air is contained in a flat bag. At least one surface of the flat bag is made air permeable so that pressure in the flat bag is reduced by exothermic reaction of the heat generating agent, and a self-adhesive layer is provided on either surface of the flat bag. Since the heat-generating agent contains high performance activated carbon having an iodine adsorption of 800 to 1200 mg/g and a methylene blue decoloring power of 100 to 300 mg/g, the rising in temperature is fast in comparison with conventional body warmers.
