PROBLEM TO BE SOLVED: To make it possible to prevent the generation of dust at the time of production of a heating element by forming an exothermic compsn. of an exothermic material, water absorptive polymer and/or thickener, carbon component and/on chloride of a metal and water as essential components and forming the entire part thereof to an inky or creamy form. ;SOLUTION: The inky or creamy exothermic compsn. 2 is enclosed into a rectangular and flat bag (packaging material) 1. This bag 1 consists of a base material 3 having air impermeability and a coating material having air permeability and is formed with a tacky adhesive layer 5 on the exposed surface of this base material. The exothermic compsn. 2 is formed of the exothermic material, the water absorptive polymer and/or the thickener, the carbon component and/or the chloride of metal and water as the essential components and is formed into the inky or creamy form as a whole. Further, at least one kind selected from inorg. or org. water retaining agents, pH control agents, surfactants and defoaming agents are compounded into the exothermic compsn. 2.;COPYRIGHT: (C)1997,JPO
