Abstract: In a proximity sensor including a circuit board on which a detection circuit is printed, and a first drive electrode and a lock electrode mounted on one surface of the circuit board and electrically connected to the detection circuit, the first planar drive electrode and the planar lock electrode are formed in a standing manner on one surface of the circuit board to face each other. A second planar drive electrode and a planar unlock electrode are formed in a standing manner on the other surface of the circuit board to face each other. The proximity sensor is used in a keyless entry device of vehicle, and the controller that controls driving of an actuator for locking or unlocking a vehicle door based on detection of the proximity sensor determines that the proximity sensor is turned on when decrease in output of the proximity sensor exceeds a predetermined threshold value.
