Abstract
An image capturing unit for an electronic endoscope is provided with a solid-state image capturing element having multiple boding wires arranged at peripheral positions on a front surface of the solid-state image capturing element, the bonding wires extending outward, an image capturing element holding frame in which the solid-state image capturing element is held and a transparent cover glass enclosing the front surface of the solid-state image capturing element from outside, together with a tip end portion of the image capturing element holding frame. The tip end portion of the image capturing element holding frame is formed to have a tubular section, the cover glass being fitted in the tubular section and located at a position where the cover glass does not contact the bonding wires, the cover glass being air-tightly cemented to the tubular section.
