Abstract

The present invention relates to a heat-generating body containing a heat-generating composition causing a heat-generating reaction in the presence of air sealed in an air permeable container body having a desired shape, such as a bag form, a sheet form and the like, and a cohesive layer provided. The invention aims to such an object that chill feeling to a human body upon application and in the initial service period, which is a problem of a water-containing hydrophilic gel, is reduced to provide a heat-generating body suitable for using as a heat-generating sheet agent or the like having a water-soluble hydrophilic gel cohesive agent layer excellent in usability, which is a heat-generating body containing a heat-generating composition causing a heat-generating reaction in the presence of air sealed in an air permeable container body having a desired shape, such as a bag form, a sheet form and the like, and a cohesive layer containing water-containing hydrophilic gel agent obtained from a hydrophilic polymer thickener provided on the container body, characterized in that the water containing hydrophilic gel agent contains an organic filler.
