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 image-signal generating apparatus comprises a solid-state image pickup device-equivalent load circuit unit including a load approximately equivalent to a solid-state image pickup device such as a charge coupled device, etc. The image-signal generating apparatus further comprises an image-signal generating circuit for generating an image signal corresponding to an output signal output from the solid-state image pickup device through the solid-state image pickup device-equivalent load circuit unit, which is a load to which a driving signal for driving the solid-state image pickup device is applied.
