PROBLEM TO BE SOLVED: To provide a heating instrument having a structure capable of locally and sufficiently warming a surface layer of a living body such as a human body.SOLUTION: A heating instrument 100 is equipped with: a sheet 10 having a projection 12 which curves so as to be convex on one surface side thereof, and have a cavity 13 formed on the other surface side thereof； and a heat-generating material 30 which is packed into the cavity 13 of the projection 12. The heating instrument 100 is mounted to a living body such as a human body while the projection 12 is pressure-welded to the skin. Consequently, while pressing the skin of the living body by the projection 12, a portion corresponding to the projection 12 in the skin of the living body can locally and sufficiently be warmed.SELECTED DRAWING: Figure 3【課題】人体等の生体の表層を局所的に十分に温めることが可能な構造の温熱具を提供する。【解決手段】温熱具１００は、一方の面側に凸に湾曲していて他方の面側が空洞１３となっている突起部１２を有するシート１０と、突起部１２の空洞１３に充填されている発熱材３０と、を備えている。突起部１２が皮膚に圧接される状態で温熱具１００を人体などの生体に装着することにより、突起部１２によって生体の皮膚を圧しながら、生体の皮膚において突起部１２と対応する部位を局所的に十分に温めることができる。【選択図】図３
