PROBLEM TO BE SOLVED: To provide an electronic endoscope satisfying a safety standard condition with low power consumption.
SOLUTION: In a distal end part 11 of the endoscope 1, an illuminating part 21 with an illuminating LED and a C-MOS 23 to take an observation image illuminated by the illuminating light are disposed. A battery 24 is arranged in an operating part 15 to supply power to the illuminating part 21 and the C-MOS 23. An image output terminal part 25 connected with an end part of a video cable 16 to output an image signal to a display device 2 is set on the base end part of the operating part 15. The battery 24, the illuminating part 21, and the C-MOS 23 are connected by a power supplying cable 26 branching into an illumination power cable 27 and an imaging element power cable 28. A current limiting circuit 29 is set midway the power supplying cable 26 to prevent excess current from flowing through the illuminating part 21 and the C-MOS 23. An image signal transmitting cable 30 extended from the C-MOS 23 is connected with the image output terminal part 25.
