Abstract: An endoscope distal end structure includes: an imager, a distal end frame that is a three-dimensional molded interconnect device including a housing portion and a cable connecting portion, the cable connecting portion including a cable connection electrode, the housing portion being formed by cutting out at least a part of an outer peripheral portion of the distal end frame, the housing portion having a bottom surface on which connection terminals are formed, and a first side surface and a second side surface which are continuous to each other and on which a ground pattern is formed, a through hole having electrical conductivity, the through hole penetrating from the bottom surface to the cable connecting portion, and an electrical conductive pattern connecting a cable connection electrode and the ground pattern, the electrical conductive pattern being arranged on a side surface of the distal end frame.

Abstract: An endoscope includes an imager unit loading region provided at a distal end portion of an insertion portion, a cable connection surface, a wall provided to connect an opening of the imager unit loading region and an opening of the cable connection surface to each other, a contact pattern formed on a wall surface of the imager unit loading region, a wiring pattern formed on a front surface of the cable connection surface from the wall, a connection pattern formed on the cable connection surface, and a through-electrode formed in the wall so that the imager unit loading region and the cable connection surface communicate with each other, configured to cause the contact pattern and the wiring pattern to electrically continue to each other, and formed at a predetermined angle with respect to a center axis of the distal end barrel member.

Abstract: An endoscope distal end structure includes: an imaging unit; a signal cable; and a distal end frame including a housing portion, and a cable connection portion configured to connect the signal cable. The housing portion is a recess formed on a distal end side of the distal end frame. The housing portion includes a side surface and a bottom surface provided with a connection terminal. At least a part of the cable connection portion is provided with a cable connection electrode that connects a core wire of the signal cable on a distal end side from a bottom surface of the housing portion with reference to the optical axis direction of the imaging unit. The connection terminal and the cable connection electrode are connected by a wiring pattern formed in the housing portion, an outer periphery of the distal end frame, and the cable connection portion.

Abstract: A holding frame for an imaging unit arranged at a distal end of an endoscope includes a cylindrical three-dimensional molded interconnect device; a housing configured to house the imaging unit, the housing being formed of a notch; at least one cut face formed on the side face of the holding frame and obtained by cutting a support portion which is a gate portion into which a resin is injected when the holding frame is resin-molded; a connection terminal formed on a bottom face of the housing portion and configured to be connected to the imaging unit; a cable connection electrode arranged on a face where a proximal end side of the holding frame is notched; and a wiring pattern formed on a surface area of the holding frame excluding the cut face and configured to electrically connect the connection terminal and the cable connection electrode.
