PROBLEM TO BE SOLVED: To provide a small-sized thermotherapy device that can be operated by patient himself/herself, and can be carried without increasing the size of the device itself and without needing to prepare a plurality of therapy devices.SOLUTION: A thermotherapy device 1 includes an electromagnetic wave generation part 2 for generating an electromagnetic wave, a power source part 3 for supplying power to drive the electromagnetic wave generation part 2, a control part 4 for controlling the output of the electromagnetic wave generated from the electromagnetic wave generation part 2, an electromagnetic wave irradiation part 5 for irradiating the electromagnetic wave generated from the electromagnetic wave generation part 2, and an electromagnetic wave transmission part 6 disposed between the electromagnetic wave generation part 2 and the electromagnetic wave irradiation part 5. Relative positions of the electromagnetic wave generation part 2 and the electromagnetic wave irradiation part 5 can be changed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】装置自体を大型化することなく、治療器を複数台用意する必要も無く、患者自身が操作可でき、持ち運び可能な小型の温熱治療器を提供すること。【解決手段】本発明に係る温熱治療器1は、電磁波を発生させる電磁波発生部2と、前記電磁波発生部2を駆動させる電力を供給する電源部3と、前記電磁波発生部2から発生する前記電磁波の出力を制御する制御部4と、前記電磁波発生部2から発生する前記電磁波を照射する電磁波照射部5と、前記電磁波発生部2と前記電磁波照射部5との間に設けられた電磁波伝達部6とを備え、前記電磁波発生部2と前記電磁波照射部5との相対位置が変更可能に設けられている。【選択図】図1
