Claim 11:
12. A distal end barrel member of an endoscope including an insertion portion configured to be inserted into a subject,
the distal end barrel member being provided at a distal end portion of the insertion portion, and comprising:
an imager unit loading region on which an imager unit configured to convert an optical image from an objective optical system into an electric signal is loaded;
a cable connection surface provided on a proximal end side;
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 and configured to be electrically connected to an electric contact of the imager unit;
a wiring pattern formed on a front surface of the cable connection surface from the wall and configured to electrically continue to the contact pattern;
a connection pattern formed on the cable connection surface and configured to electrically continue to the wiring pattern, with a core wire of a cable placed in the insertion portion being electrically connected to the connection pattern; and
a through-electrode formed on an inner surface of a through-hole that penetrates through the wall so as to connect the opening of the imager unit loading region and the opening of the cable connection surface to 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.
