A sensor for detecting a target in a non-contact manner includes a first electrode; a second; a third electrode that is disposed between the first electrode and the second electrode; and a determination circuit that, in operation, detects entry of the target into a first region by detecting a change of first electrostatic capacitance, which is electrostatic capacitance of the first electrode, and detects entry of the target into a second region by detecting a change of second electrostatic capacitance, which is electrostatic capacitance of the second electrode. An electric potential of the third electrode is more negative than electric potentials of the first electrode and the second electrode. At least a part of the second region at least partially surrounds an outer edge of the first region in plan view.
