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.

Abstract: An image capturing unit for an electronic endoscope, including a solid-state 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 solid-state 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 external, is provided. 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 glass is hermetically sealed to the frame.

Abstract: An aluminum alloy material for forging obtained by a continuous casting process, the alloy comprising: a surface of which roughness is not more than Ra 35, and a segregation layer having 0.1 to 2 mm thickness and generated in the surface. The cast surface after continuous casting is smooth without peeling, a cast material can be forged without any treatment, and a segregation layer remains in a surface layer, thereby inhibiting coarsening of recrystallization grains and exhibiting superior toughness and strength.

Abstract: A microminiature CCD image pickup device with a shortened length that can be applied to an electronic medical endoscope or the like. Microminiature CCD image pickup device (1) has optical glass (11), CCD chip (12), and stacked circuit board (15) that are disposed in that order along its length orientation. It further has TAB tape (13) that connects CCD chip (12) and the electronic circuits mounted on stacked circuit board (15). Stacked circuit board (15) is formed with insulated circuit board in which are packaged electronic circuits, including their wiring pattern, stacked in stacked layers in the diametral direction perpendicular to said length orientation, and has at least one cavity (153) formed as an indention in the diametral direction. At least one miniature chip component (16) is mounted in cavity (153), and at least one chip component (17) is mounted on the surface of stacked circuit board (15) over cavity (153).
