Abstract: An electronic endoscope has an insert section to be introduced into a human body cavity. A distal portion of the insert section contains a CCD and a printed circuit board to which the CCD is bonded. In the insert section, a cable bundle being a bundle of coaxial cables extends. Each coaxial cable consists of a signal line, insulation surrounding the signal line, a braided wire surrounding the insulation, and an insulating jacket. The cylindrical braided wire is stranded into a single line, and is soldered as a ground line to a ground terminal of the printed circuit board. The signal line is pulled out of the coaxial cable with a length longer than the ground line. The signal line is soldered to an input/output terminal of the printed circuit board with a larger sag than the ground line.

Abstract: A connector includes a cable attachment ring that fits onto a signal cable, a circuit board attachment part that catches a circuit board, and a connecting pillar that connects the cable attachment ring and the circuit board attachment part. The cable attachment ring is detachable from the signal cable, and the circuit board attachment part is detachable from the circuit board.
