<p>An endoscope has a section of an elongated tube (14) for entry in a body cavity. An end shell (35) is disposed at a distal end of the elongated tube. An imaging window area (40) is formed in the end shell. A lens barrel (52) is secured to the end shell, and aligned with the imaging window area. An imaging device (56) photoelectrically detects object light from the lens barrel. A circuit board (57) has the imaging device mounted thereon. A signal cable (25) has a cover material (66), and plural filaments (65) covered by the cover material, and connected to the circuit board. A cable retaining device (61) partially retains the cover material fixedly. A tip portion (69) is formed at a distal end of the cable retaining device. A coupling device (86) keeps the tip portion laterally movable on the end shell, to prevent stress in the cable retaining device from exertion to the end shell.</p> |
