PROBLEM TO BE SOLVED: To provide a heating implement which keeps the adhesion between sheet-like heating elements suppressed, and the reduction of the fitting property of the heating implement, and the generation of a feeling of congruity effectively prevented from occurring.SOLUTION: This heating implement 10 has a plurality of sheet-like heating elements 20 which are stacked. Then, layers 21 and 22 which suppress the adhesion of the sheet-like heating elements 20 to each other resulting from heating are installed in a space between the adjacent sheet-like heating elements 20 for the heating implement 10. The layer 21 is preferably constituted by containing a solid fat, a lubricant or a non-aqueous antioxidant. The layer 22 preferably consists of an air-permeable sheet having heat resistance at the heating temperature of the sheet-like heating elements.COPYRIGHT: (C)2009,JPO&INPIT【課題】シート状発熱体どうしの癒着が抑制され、発熱具の装着性の低下や違和感の発生が効果的に防止された発熱体を提供すること。【解決手段】複数枚積層されたシート状発熱体20を有し、隣り合うシート状発熱体20間に、発熱に起因するシート状発熱体20どうしの癒着を抑制する層21,22が設けられている発熱具10。層21は、固形脂、滑沢剤又は非水系抗酸化剤を含んで構成されていることが好ましい。層22は、前記シート状発熱体の発熱温度において耐熱性を有する通気性シートからなることが好ましい。【選択図】図3
