Summary:An electric endoscope includes a motor that generates a rotational driving force, a torque shaft that transmits the rotational driving force from a proximal end portion to a distal end portion, a connecting section for bending a bending portion by the rotational driving force transmitted by the torque shaft, an input section that instructs a target rotation amount of the motor, a detecting section that detects rotation information of the motor in a rotating state thereof, an estimating section that estimates a rotation state of the motor based on the rotation information, a motor physical model, a torque shaft physical model and a connecting section physical model, and a control section that performs control so that the rotation state of the distal end portion matches with a rotation state of the target rotation amount based on the estimated rotation state of the motor.
