PROBLEM TO BE SOLVED: To provide an electronic endoscope of a new structure accurately acquiring detailed video information in a wide range. SOLUTION: The electronic endoscope includes: a cylindrical transparent body 3 wherein at least the observation window of a cylindrical part is transparent; a body part 2 which is provided with a cylindrical part connected to the cylindrical part of the transparent body 3; a rotating body 4 which is rotated around the center axis of the transparent body 3 inside the transparent body 3 and the body part 2, and moved in the center axis direction; an objective mirror 16 which is provided on the rotating body 4 and reflects light made incident through an objective lens 17 provided on a position facing the cylindrical part of the transparent body 3 in the direction of the body part 2; a driving means 28 which is provided inside the body part 2 and moves the rotating body 4 so that an imaging visual field obtained through an imaging hole 4f overlaps at least by a half pitch each at least when rotationally driving the rotating body 4 or when driving it in the center axis direction; and an imaging element 27 which receives light reflected by the objective mirror 16 for each imaging visual field moved at least by a half pitch and converts it to electric signals.
