<p>The present invention addresses the problem of providing: a heat generating composition that achieves an excellent heating property (heat generation increasing property) by promoting an oxidation reaction, has excellent heat generating capabilities such as long-lasting heat generation temperature sustainability (heat generation sustainability), is easily manufactured, and yet also has excellent economic efficiency; and a disposable body warmer using the same. A heat generating composition which contains an oxidisable metal powder, an inorganic electrolyte, water, a carbon component, and a water-retention agent, and generates heat in the presence of air. The carbon component uses carbon black having a DBP absorption amount of 49-150cm3/100g, and the obtained heat generating composition is housed in a bag to produce a disposable body warmer.</p> |
