Abstract
An endoscope includes a sensor, and a temperature compensation circuit configured to perform temperature compensation of an output signal of the sensor, in a distal end portion. The temperature compensation circuit includes a differential amplifying section configured to amplify an output signal of the sensor, and a temperature sensing section in which a resistance is connected in series to a parallel connection portion of a temperature sensing element and a resistance.
