This therapeutic treatment device (100) is a device for treating a biological tissue by heating same at a target temperature and comprises: a treatment tool (120) a storage unit (123 187) and a control device (170). The treatment tool includes: a heat transfer unit (132, 134) that transfers heat to the biological tissue and a resistance element (140) that heats the heat transfer unit by being supplied with electric power. The storage unit stores a time/electric power list. The control device includes: a resistance value acquiring unit (184) that acquires the resistance value of the resistance element an electric-power supply unit (183) that supplies electric power to the resistance element and a control unit (180). The control unit: makes the electric-power supply unit supply electric power for state detection during a state detection period calculates the change in the resistance value during the state detection period on the basis of the resistance value acquired by the resistance value acquiring unit acquires, from the time/electric power list, the time/electric power relationship corresponding to the change in the resistance value and makes the electric-power supply unit supply electric power based on the acquired time/electric power relationship after the state detection period has elapsed.Le dispositif (100) de traitement thérapeutique selon linvention est un dispositif permettant de traiter un tissu biologique en le chauffant à une température cible et comprend : un outil (120) de traitement une unité de stockage (123 187) et un dispositif (170) de commande.
