Abstract
An image capturing unit for an electronic endoscope, including a solid-state image capturing element, a metallic housing member, which hermetically encloses a circumference of an insulated base and is arranged to cover a front-end portion of the insulated base, at least one connection land, which is connected to at least one signal conductor at a position in vicinity to a rear-end portion of the insulated base outside the housing member, and a conductive cylindrical shield, which surrounds the at least one connection land and the at least one signal conductor and is spaced from the at least one connection land and the at least one signal conductor in a radial direction, is provided. An outer periphery of the rear-end portion of the insulated base is formed to be smaller than the circumference of the insulated base enclosed by the housing member.
