Abstract
An imaging unit provided at a tip portion of an endoscope includes: an imaging element configured to receive light and perform photoelectric conversion on the light to generate an electrical signal; an oscillator configured to generate a clock signal for driving the imaging element; a photoelectric element configured to convert the electrical signal generated by the imaging element into an optical signal and to output the optical signal to outside; a regulator configured to convert electric power input from the outside into electric power depending on each of the imaging element, the oscillator, and the photoelectric element, and to supply the converted electric power thereto. The imaging element is spaced farther than the oscillator and the photoelectric element from the regulator.
