Abstract
An endoscope system includes an imaging element, a voltage-current conversion circuit, a first coaxial cable, and an impedance conversion circuit. The imaging element generates a first voltage. The voltage-current conversion circuit is disposed inside or outside the imaging element and converts the first voltage into a first current. The first coaxial cable has a first conductor and a second conductor. The second conductor is disposed outside the first conductor. The first current is transmitted through the first conductor. The first current transmitted through the first conductor is input to the impedance conversion circuit. The impedance conversion circuit outputs a second current according to the first current. A second voltage according to the first current is input to the second conductor.
