PURPOSE:To provide the novel heat generator comprising sugar and an inorganic salt generating heat in the presence of water, easily handled, free from the anxiety of a fire, not restricting a specific place for heating and thermally insulating foods, and easily disposable after use. CONSTITUTION:The heat generator generating heat by the contact of water comprises (A) an inorganic salt generating heat in the presence of the water and (B) sugar preferably in a weight ratio of 100:50-150. The component A is preferably magnesium chloride having good safely and high solubility in water. When the elongation of the heat-generating time is required granular sugar or powder sugar is preferably used as the component B. The amount of water used for the heat generator is preferably 50-200 pts.wt. per 100 pts.wt. of the component A in the heat generator. |
