Abstract
A detection sensor includes: a detection electrode that is disposed in at least one of a vehicle door and a periphery of the vehicle door and used for detecting operation of the vehicle door; an area electrode that is disposed in the vehicle door; and a control device that detects an electrostatic capacitance change of the detection electrode and an electrostatic capacitance change of the area electrode, in which the control device performs at least one of determining of detection of an object in a periphery of the detection electrode using the detection electrode, and determining of detection of an object in a periphery of the area electrode using the area electrode depending on an open or closed state of the vehicle door.
