<p>There are provided such a heat-generating body for warming foot in that a heat-generating composition is used that can retain the shape thereof irrespective of the pressure inside the container bag upon using by application to a foot, a footgear or a sock, the heat-generating composition is prevented from migration by fixing a part or a whole thereof inside the packing material, and it is well fit to the shape of the foot upon application to warm the prescribed part effectively for a long period of time, and such a process for producing a heat-generating body for warming foot in that the heat generation reaction of the heat-generating composition is suppressed to prevent loss due to the heat-generating reaction during production, quality deterioration of the heat-generating composition, and various problems associated with solidification of the heat-generating composition, a transferring and laminating method, such as printing, coating , such as mold-through forming, gravure printing, is employed, the non-viscous heat-generating composition can be uniformly distributed, the accuracy of lamination is further improved to attain stabilization in quality of the product, and heat-generating bodies for warming foot of an ultrathin form to a thick shape can be easily produced at low cost. A heat-generating body for warming foot of the invention is characterized in that it contains a heat-generating formed article causing a heat-generating reaction in the presence of air and having a shape retaining degree of 70 or more charged in a container bag constituted with a base material, a covering material and the like, and the container bag has air permeability at least at a part thereof. <IMAGE></p> |
