PROBLEM TO BE SOLVED: To provide a method for manufacturing a heating implement, capable of continuously and efficiently manufacturing the heating implement excellent in heating characteristic of a heating element, hardly causing delamination, and having both heat giving function and function excluding heat giving function.SOLUTION: A method for manufacturing a heating implement includes an agent liquid coating step of forming an agent holding sheet 4 by partially coating an agent liquid 7 so as to include a coating part 7a and a non-coating part 7b of the agent liquid 7 obtained by melting an agent with a solvent, on one surface of a belt-like agent holding sheet 4B. Furthermore, there are included: after the agent liquid coating step, an exothermic composition coating step of obtaining a belt-like lamination structure precursor 2A by coating an exothermic composition 3A so as to superpose the coating part 7a and the non-coating part 7b of the agent liquid on one surface side of the agent holding sheet 4 partially coated with the agent liquid 7； and after the exothermic composition coating step, a cutting step of obtaining a sheet type lamination structure precursor 2A by cutting the belt-like lamination structure precursor 2A to a prescribed length.SELECTED DRAWING: Figure 3【課題】発熱体の温熱特性が良好で、層間剥離が生じ難い、温熱付与と温熱付与以外の機能とを併せ持つ温熱具を連続して効率的に製造することができ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、帯状の液保持性シート４Ｂの一面に、薬剤を溶解剤で溶解した薬液７の塗工部分７ａと未塗工部分７ｂとを有するように部分的に薬液７を塗工して薬剤保持シート４を形成する薬液塗工工程を備える。また、薬液塗工工程の後、薬液７を部分的に塗工した薬剤保持シート４の一面側に、薬液の塗工部分７ａ及び未塗工部分７ｂと重なるように、発熱組成物３Ａを塗工して帯状の積層構造体前駆体２Ａを得る発熱組成物塗工工程を備える。そして発熱組成物塗工工程の後、帯状の積層構造体前駆体２Ａを所定長さに切断して枚葉の積層構造体前駆体２Ａを得る切断工程を備える。【選択図】図３
