PROBLEM TO BE SOLVED: To provide a hyperthermia tool capable of pressing a skin of a living body such as a human body by a protrusion part with higher comfortableness.SOLUTION: A hyperthermia tool comprises: a sheet-state body sheet having a heating element； and a protrusion part sheet which is provided on one surface of the body sheet. The protrusion part sheet comprises salient-state protrusion parts on one side, and when magnitude of a load when the protrusion parts are pressed to a direction being opposite to a protrusion direction of the protrusion parts, is a first axis, and a collapse amount of the protrusion parts is a second axis, a profile of relationship between the load and the collapse amount comprises a first region R1 in which, the collapse amount is increased following to increase of the load, and a second region R2 in which a value on the first axis is at a large side relative to that in the first region R1, and an increase ratio of the collapse amount following to increase of the load is larger than that in the first region R1, in the direction of the first axis, a range of the second region R2 is wider than a range of the first region R1.SELECTED DRAWING: Figure 12COPYRIGHT: (C)2020,JPO&INPIT【課題】突起部によって人体等の生体の皮膚をより心地よく押圧することが可能な温熱具を提供する。【解決手段】温熱具は、発熱体を有するシート状の本体シートと、本体シートの一方の面に設けられている突起部シートとを備え、突起部シートは、上記一方の側に凸の突起部を有し、突起部を当該突起部の突出方向に対する反対方向に押圧する際の荷重の大きさを第１軸とし、当該突起部の潰れ量を第２軸とすると、上記荷重と上記潰れ量との関係のプロファイルは、荷重の増大に伴って潰れ量が増大する第１領域Ｒ１と、第１領域Ｒ１よりも第１軸における値が大きい側に位置していて荷重の増大に伴う潰れ量の増大比率が第１領域Ｒ１における増大比率よりも大きい第２領域Ｒ２と、を含み、第１軸の方向において、第１領域Ｒ１の範囲よりも第２領域Ｒ２の範囲が広い。【選択図】図１２
