Abstract
An operation detection device includes an electrostatic sensor accommodated inside a casing and including a first conductor and a second conductor, and a controller electrically connected to the first conductor and the second conductor, and applies a voltage to each of the first conductor and the second conductor, to measure an electrostatic capacitance of each of the first conductor and the second conductor. The first conductor is arranged in and the second conductor is not arranged in a detection region in which an operating body is detected by the electrostatic sensor. The first conductor and the second conductor are arranged in a non-detection region in which the operating body is not detected.
