A therapeutic treatment apparatus for heating and treating a body tissue at a first target temperature comprises a heat transfer part (110), a heat generation member (140), a first temperature acquisition part (373), a second temperature acquisition part (373), a control part (371), and a power supply part (372). The heat generation member heats the heat transfer part. The first temperature acquisition part acquires a temperature of the heat generation member as a first temperature. The second temperature acquisition part acquires a temperature of the heat transfer part as a second temperature. The control part determines power to be supplied to an electric resistance pattern by feedback control using the first temperature such that a temperature of the heat transfer part reaches the first target temperature based on a temperature difference between the first target temperature and the second temperature. The power supply part supplies the electric resistance pattern with power under control of the control part.
