An electric bending endoscope includes a temperature sensor that detects the temperature of a motor as a state value indicating the driving state of a bending drive unit. A bending control device comprises: a temperature detection unit that receives the data of the temperature detected by the temperature sensor; a record unit in which the limits of motor temperature inputted in advance are recorded; a comparison unit that compares the data of the temperature sent from the temperature detection unit with the limits of motor temperature recorded in the record unit; and a notification unit that notifies that the driving state of a motor is approaching the limit.
