An endoscope is provided and includes a flexible insertion tube; a distal end assembly provided at an end of the insertion tube; and a cooling medium tube provided in the inside of the insertion tube, and connected to the distal end assembly. A cooling medium for cooling the distal end assembly is introduced through one of the insertion tube and the cooling medium tube, and discharged through the other of the insertion tube and the cooling medium tube. Since the endoscope is configured such that the cooling medium directly contacts with a heating element or a conductor through which the heat of the heating element is conducted, the cooling effect of the front end portion of the endoscope is improved.

An image stabilizer is provided, which compensates for an external turbulence caused by hand-shake by moving an imaging unit. The image stabilizer includes a first yoke, a second yoke, and a driving frame interposed between the first yoke and the second yoke and movable in a vertical direction, a horizontal direction, and a rotation direction with respect to an optical axis. The imaging unit is mounted in a center of the driving frame. The image stabilizer also includes a coil plate connected to a surface of the driving frame facing the first yoke and having a plurality of pattern coils arranged at locations corresponding to a plurality of magnets of the second yoke. The image stabilizer further includes a support unit disposed on a surface of the driving frame facing the second yoke and supporting the driving frame in pitch, yaw and roll directions with respect to the second yoke.
