Abstract: A door handle includes a door handle case and an electrostatic sensor provided in the door handle case. The electrostatic sensor includes a detection electrode that is formed of a flat conductor plate, or that is formed on a surface of a flat substrate or within a flat substrate. The detection electrode includes a middle portion in a longitudinal direction of the detection electrode and includes peripheral portions proximal to both end portions of the detection electrode in the longitudinal direction. For a width of the detection electrode in a direction perpendicular to the longitudinal direction, each peripheral portion is wider than the middle portion, and the width of the detection electrode gradually increases toward each end portion in the longitudinal direction.

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.

Abstract: A door handle includes door handle case, a first detection electrode and a second detection electrode disposed in the door handle case, and a controller connected to the first detection electrode and the second detection electrode. The controller separately measures a first capacitance between the first detection electrode and an operation body and a second capacitance between the second detection electrode and the operation body, and the controller determines whether a locking operation is performed by the operation body based on one or both of the first capacitance and the second capacitance.
