PURPOSE: To provide the tacky adhesive heating element which is adequate for industrial production, is not hindered in tackiness (initial tackiness) and tacky adhesive power in a low to high temp. region at the time of mounting the tacky adhesive heating element and does not generate the glue transfer to an adherend.
CONSTITUTION: This tacky adhesive heating element is produced by housing a exothermic agent which generates heat in the presence of air in an exothermic agent housing bag, of which the one surface consists of a base material sheet provided with a tacky adhesive on its outside surface and the other surface consists of an air permeable packaging material. The tacky adhesive is a hot melt type adhesive containing a styrene-based block copolymer, a rosin-based ester, a tackifier exclusive of the rosin-based ester, a plasticizer and a stabilizer.
