Abstract: A heating treatment apparatus to treat a living tissue by heating the living tissue includes a first holding member and a second holding member, a first heat generating element provided on the first holding member, a second heat generating element provided on the second holding member, a power supply unit supplying electric power to cause the first heat generating element and the second heat generating element to generate heat, and a control unit controlling operations of the power supply unit. The control unit switches a mode between a first mode and a second mode during treatment of the living tissue. Temperatures of the first heat generating element and the second heat generating element are controlled to the same temperature in the first mode and to different temperatures in the second mode.
