PROBLEM TO BE SOLVED: To provide a method of manufacturing a warmer, which stably provides a warmer with high quality having both a heat giving function and a function other than giving heat.SOLUTION: The method of manufacturing a warmer is the method of manufacturing the warmer which includes the lamination body 4 constituted of a heat generation body 2, where an exothermic composition 8 containing metal to be oxidized contains an electrolyte aqueous solution, and of a liquid chemical containing sheet 3, where a liquid holding sheet 9 contains a liquid chemical containing a lipophilic medicine and the dissolving agent of the medicine. The method includes: a process for applying the liquid chemical to one surface of a belt shape liquid holding sheet 9 through the use of a contact type liquid chemical applying means 31, and then, obtaining a belt shape lamination body precursor 10 by superimposing the liquid holding sheet 9 on a belt shape exothermic composition 8, so as to allow one surface of the liquid holding sheet 9 to face the exothermic composition 8 and a process for cutting the belt shape lamination body precursor 10 by prescribed length to obtain the sheets of lamination body precursors 10, and applying the electrolyte aqueous solution to the sheets of lamination body precursors 10 so as to obtain the lamination bodies 4.COPYRIGHT: (C)2011,JPO&INPIT【課題】温熱付与と温熱付与以外の機能とを併せ持つ高品質の温熱具を安定的に提供し得る温熱具の製造方法を提供すること。【解決手段】本発明の温熱具の製造方法は、被酸化性金属を含む発熱組成物8に電解質水溶液を含有させてなる発熱体2と、液保持性シート9に親油性の薬剤及び該薬剤の溶解剤を含む薬液を含有させてなる薬液含有シート3との積層体4を備えた温熱具の製造方法である。帯状の液保持性シート9´の一面に、接触型の薬液塗布手段31を用いて、薬液を塗布した後、液保持性シート9´と帯状の発熱組成物8´とを、液保持性シート9´の該一面が発熱組成物8´と対向するように重ね合わせて帯状の積層体前駆体10´を得る工程と、帯状の積層体前駆体10´を所定長さに切断して枚葉の積層体前駆体10とし、枚葉の積層体前駆体10に電解質水溶液を塗布して積層体4を得る工程とを備えている。【選択図】図3
