<p><P>PROBLEM TO BE SOLVED: To prevent a distal end portion and an insert part from being influenced by hear, by effectively dissipating and radiating heat generated by an actuator. <P>SOLUTION: An endoscope 2 includes: a break-proof part 11 connecting the operation part 10 and insert part 9 of the endoscope 2; a lens drive wire 42 for moving a movable lens 36 of an optical system disposed within the insert part 9 forward and backward in an optical axis direction; and an actuator 50, which generates heat during driving, for driving the lens drive wire 42. At least a part of a heat conduction member 80 is disposed within the break-proof part 11, wherein the heat conduction member 80 is connected with the actuator 50 in the case where the actuator 50 is disposed within the break-proof part 11 or the actuator 50 is disposed within the insert part 9. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
