Patent number: 7491167Abstract: An image capturing unit for an electronic endoscope, includes an image capturing element with an image capturing area, at least one bonding wire, which is extended curvedly and outwardly from at least one edge portion of a surface of the image capturing element to at least one conductor, and a transparent cover plate, which is fixed to a frame and is adapted to seal the image capturing element from an external environment. The cover plate is formed to have at least one bonding wire preventing portion, which is adapted to prevent the at least one bonding wire from being in contact with the cover plate. An edge portion on a front surface of the cover plate is hermetically sealed to the frame.Type: GrantFiled: June 30, 2006Date of Patent: February 17, 2009Assignee: Hoya CorporationInventors: Takayuki Ogino, Kazuyuki Yamamoto, Akihiro Ito, Seiichiro Okamura, Tomokazu Yamashita
