ABSTRACT:
A sheet-shaped heat-generating body comprising a sheet-shaped substrate comprising irregularly arranged fibers and having a multiplicity of gaps among the fibers, an oxidizable metal powder dispersed in and supported by the substrate, and an inorganic electrolyte solution containing activated carbon mixed and suspended therein with which the substrate supporting the oxidizable metal powder dispersed therein is impregnated. Since the entire structure of the sheet-shaped heat-generating body is integrated, with the fibrous and porous sheet-shaped substrate assuring uniform distribution and firm support of the oxidizable metal powder or the heat-generating substance, the body is flexible, is free from one-sided distribution of the heat-generating substance, and has excellent heat generating capability.
