摘要:
An electronic endoscope includes a lens holder that has a tube-shaped part, a wide-angle lens that is mounted on the lens holder and that is arranged on one-end side of the tube-shaped part in a state that an optical axis is aligned to a center axis of the tube-shaped part so that an observational field of view extends to a sideward region of the tube-shaped part, an imaging device that receives light acquired through the wide-angle lens and that converts the light into an electric signal, a transparent cover that covers one-end side of the tube-shaped part and whose part facing the observational field of view of the wide-angle lens has transparency, a tube-shaped body part that is connected to the transparent cover on the-other-end side of the tube-shaped part, and a driving section that causes the lens holder to advance or retreat in the center axis direction.
