Abstract: An endoscope includes: a composite cable in which a plurality of cables each including a core wire and an electric insulating coated portion coating the core wire are bundled with an electric insulating outer sheath; a substrate that includes electrodes to which the respective cables are connected; and a cable fixing portion that includes a cable distal end fixing portion holding the plurality of cables in which the core wire and the coated portion are exposed from a distal end surface side of the composite cable, a cable alignment portion aligning the plurality of cables, and a cable body fixing portion holding an end portion of the composite cable on a side where the plurality of cables is exposed, and provided with a through hole having a diameter same as a diameter of an outer periphery of the composite cable.

Abstract: An image pickup unit for use with an endoscope comprises: a first wiring board in which a first surface, a plurality of first pads are disposed on the first surface, and a plurality of second pads are disposed on the first surface; and a second wiring board in which a second surface comprises a first region and a second region spaced apart from the first region, a plurality of first lands are disposed on the first region, the plurality of first lands are solder-bonded to the plurality of first pads, and a plurality of second lands are disposed on the second region, the plurality of second lands are solder-bonded to the plurality of second pads, and a sum of areas of the plurality of first pads is substantially same as a sum of areas of the plurality of second pads.

Abstract: The image pickup unit includes an image pickup device, a first substrate, and a second substrate that are connected in this order. The second substrate includes a side surface formed in a direction crossing a light-receiving surface of the image pickup device. The second substrate includes, in the side surface thereof, a recessed portion into which a jig is inserted to hold the image pickup unit.

Abstract: An image pickup unit includes: an image pickup device, a first wiring board bonded to the image pickup device; and a second wiring board bonded to the first wiring board and including a gate remnant in a back area of the second wiring board.

Abstract: A three-dimensional circuit board connected to a back surface of a plane circuit board includes a front surface corresponding to the back surface of the plane circuit board, an upper surface and a lower surface intersecting the front surface, a first connection electrode provided on the front surface, a second connection electrode extended from the first connection electrode to the upper surface and the lower surface, and a resist layer covering the second connection electrode in each of regions on the upper surface and the lower surface and near the front surface.

Abstract: An image pickup unit includes: an image pickup device; a flat circuit board; a three-dimensional circuit board; plural electronic components; and plural cables, in which the three-dimensional circuit board includes: a first surface; a second surface; a third surface; a fourth surface; a fifth surface; and a sixth surface, in which on one of the first surface to the sixth surface, a recessed portion is formed and a connection terminal portion is formed in an inner surface of the recessed portion, one of the plural electronic components or the plural cables is mounted on or connected to the connection terminal portion, the recessed portion is formed, in a site where the first surface and the sixth surface cross each other, from the second surface toward the third surface, the recessed portion having a wall surface parallel to the second surface, and one of the electronic components is mounted.
