    摘要: A warming device containing a topsheet to be located close to a skin of a user, a backsheet to be located far from the skin of the user, and a heat generating element interposed between the topsheet and the backsheet. The heat generating element contains an oxidizable metal, a carbon material, an electrolyte, and water, the heat generating element is configured to generate vapor from the heat generating element itself as heat is generated, the topsheet includes a breathable fiber sheet including fibers containing at least a polyethylene terephthalate resin, and the topsheet contains first fibers having a fiber diameter of more than 15 μm in plan view as measured by observation under a scanning electron microscope.

    摘要: This invention provides a heating tool that is capable of significantly suppressing a reduction of an active ingredient contained in an adhesive layer. More specifically, the invention provides a heating tool comprising an exothermic composition containing an oxidation accelerator, an oxidizable metal powder, and water; an active ingredient-containing adhesive layer; and a vapor deposition layer, the exothermic composition being housed in an air-permeable container bag, the vapor deposition layer being disposed between the container bag and the adhesive layer.
