A steam-generative warming devicehaving a steam generating elementthat releases steam in association with heat generation accompanying the oxidation of an oxidizable metal. The steam generative warming devicecontains a capsaicin analog and a menthol in a capsaicin analog/menthol mass ratio of 1/300 to 1/20000. It is preferred that the capsaicin analog be present in an element adapted to be brought into direct contact with the user's skin and the menthol be present in an element adapted not to be brought into contact with the user's skin.

Steam-generative warming device

A heat generating device includes a heat generating element enclosed in an air-permeable stretch bag. The heat generating element includes an air-permeable first side adapted to be located proximal to the skin of a wearer, a second side adapted to be located distal to the skin of a wearer, and a heat generating member interposed between the first side and the second side. It is preferred that a part of the heat generating element is fixed to a part of the inner side of the stretch bag in the overlap between the stretch bag and the heat generating element in a plan view of the heat generating device.
