Abstract
An electronic endoscope system comprises an insertional part at least part of whose armor is a conductor, an imaging unit incorporated in the insertional part and realized with a solid-state imaging device, a signal transmitting device for transmitting an electric signal that results from photoelectric conversion performed by the solid-state imaging device, and a signal processor for transforming an electric signal transmitted by the signal transmitting device into a video signal. The conductor serving as the armor of the insertional part is electrically isolated from the imaging unit, signal transmitting device, signal processor, and around.
