<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a heating element having stable heating characteristic. <P>SOLUTION: This is a method of manufacturing the heating element where a layer of an exothermic composition including particles of oxidizable metal, electrolyte and water is provided on a base material sheet 1. This method includes: a process of adding the electrolyte to one surface of the base material sheet 1 in the solid state; and a process of coating a paint including the particles of the oxidizable metal and water, not including the electrolyte. In this method, the above processes are performed in order, or in the reverse order, or both processes are performed at the same time. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
