Claim 0:
1. An endoscope distal end structure comprising:
an imaging unit comprising an image sensor configured to capture an image of a subject;
a plurality of signal cables configured to transmit and receive a signal to and from the imaging unit; and
a distal end frame that is a three-dimensional circuit component, the distal end frame comprising:
a housing portion being recessed from an outer periphery and from a distal end face of the distal end frame, the housing portion being configured to house the imaging unit, and
a cable connection portion configured to connect the plurality of signal cables, wherein

the housing portion includes a proximal surface offset from the distal end face in an optical axis direction of the imaging unit and a side surface offset from the proximal surface, and the proximal surface is provided with a plurality of imaging unit connection terminals respectively corresponding to the plurality of signal cables for electrically connecting the imaging unit,
the cable connection portion is provided with a plurality of cable connection electrodes respectively corresponding to the plurality of imaging unit connection terminals, each cable connection electrode of the plurality of cable connection electrodes connecting a core wire of each respective signal cable of the plurality of signal cables, all portions of the plurality of cable connection electrodes are distal to the proximal surface of the housing portion in the optical axis direction of the imaging unit, and
the plurality of imaging unit connection terminals and the plurality of cable connection electrodes are respectively connected by a wiring pattern formed in the housing portion, on an outer periphery of the distal end frame, and in the cable connection portion.
