1. An exothermic device comprising a thin flat pouch having opposed inner surfaces, a thin substrate and a thin covering material, at least a portion of said thin pouch is gas-permeable and water absorbable, said thin pouch being provided with a non-odor producing fluid exothermic composition laminated and sealed therewithin, said fluid exothermic composition comprising an exothermic substance,at least one further component selected from the group consisting of water absorptive polymer and a tackifier, at least one further component selected from the group consisting of a carbon component and metal halide, a water content in the composition which is greater than that required as an optimum amount for an exothermic reaction to occur, said exothermic composition is formed as a viscous fluid, and a portion of said water present in said viscous fluid exothermic composition is absorbed by said thin pouch, and said substrate and said covering material are sealed together by a heating technique around at least a part of the area surrounding said viscous fluid exothermic composition.
