An electrostatic capacitance sensor includes first detection electrodes and second detection electrodes that are disposed orthogonal to each other. Each of the first detection electrodes and the second detection electrodes has detection faces that are linearly arranged and connection portions that connect the two adjacent detection faces. The electrostatic capacitance sensor has intersections of the first detection electrodes and the second detection electrodes, the intersections being arranged in a matrix. The intersections where resistors are provided at the connection portions of the first detection electrodes and the intersections where resistors are provided at the connection portions of the second detection electrodes are alternately arranged.

Electrostatic capacitance sensor and input device

A detection device includes an upper detection electrode, a lower detection electrode disposed under the upper detection electrode in an overlapping manner, a proximity state detection unit configured to detect a proximity state of a detection target relative to a detection surface based on a change in at least one of electrostatic capacitances of the upper detection electrode and the lower detection electrode, and a switching unit configured to perform switching between a first state in which the upper detection electrode and the lower detection electrode are insulated from each other and a second state in which the upper detection electrode and the lower detection electrode are short-circuited to each other.
