PROBLEM TO BE SOLVED: To provide a heating tool that hardly shifts from a mounting part even if being mounted for a long time and can sufficiently exert a heating effect on an affected part.SOLUTION: A heating tool 1 comprises: a cylindrical holder 2 that has stretchability and of which both axial ends are open; and at least one band 3 that has stretchability and fixes the holder 2 to a human body by being wound around the human body. The holder 2 comprises at least one housing part 4 that can house a heat generating material. The band 3 is attached to a position shifted axially from the housing part 4 of the holder 2.SELECTED DRAWING: Figure 5【課題】長時間装着した場合でも装着部位からずれにくく、患部に温熱効果を十分に付与できる温熱具を提供する。【解決手段】温熱具1は、伸縮性を有し、軸方向の両端が開口している円筒状のホルダー2と、伸縮性を有し、人体に巻き付けられることによりホルダー2を人体に固定する少なくとも1つのバンド3とを備える。ホルダー2は、発熱材を収納可能な収納部4を少なくとも1つ備える。バンド3は、ホルダー2の収納部4とは軸方向にずれた位置に取り付けられている。【選択図】図5
