PROBLEM TO BE SOLVED: To provide a therapeutic treatment device capable of highly accurately performing heating control while reducing a size and a thickness thereof.SOLUTION: The therapeutic treatment device is provided with: a heating sheet 87 comprising a heating electric resistance pattern 8723 formed on one surface thereof, the heating electric resistance pattern 8723 generating heat by energization a heat transfer sheet provided so as to face the one surface, for transmitting the heat from the heating sheet 87 to a biological tissue by coming in contact with the biological tissue and a temperature-measuring electric resistance pattern 8734 provided on the one surface, for detecting a temperature of the heat transfer sheet. The heating electric resistance pattern 8723 comprises a first pattern part 8724 and a second pattern part 8725 having a resistance value higher than that of the first pattern part 8724. When the one surface is virtually partitioned into a first region Ar1 that includes the first pattern part 8724 and a second region Ar2 that includes the second pattern part 8725, the temperature-measuring electric resistance pattern 8734 is provided in the first region Ar1.COPYRIGHT: (C)2016,JPO&INPIT【課題】小型化及び薄型化を図りつつ、高精度に加熱制御を行うことができる治療用処置装置を提供すること。【解決手段】治療用処置装置は、通電により発熱する発熱用電気抵抗パターン8723が一方の面に形成された発熱シート87と、当該一方の面に対向して配設され、生体組織に接触して発熱シート87からの熱を生体組織に伝達する伝熱板と、当該一方の面に設けられ、伝熱板の温度を検出する測温用電気抵抗パターン8734と、を備える。発熱用電気抵抗パターン8723は、第1パターン部8724と、第1パターン部8724よりも抵抗値の高い第2パターン部8725と、を備える。測温用電気抵抗パターン8734は、第1パターン部8724を含む第1領域Ar1と第2パターン部8725を含む第2領域Ar2とに当該一方の面を仮想的に区画した場合に、第1領域Ar1に設けられている。【選択図】図5
