An input device includes a plurality of first electrodes each extending in a first direction and arrayed along a second direction crossing the first direction at a first separation distance, and a detection unit configured to detect an output signal based on electrostatic capacitance of each of the plurality of first electrodes. In addition, each of the plurality of first electrodes includes a plurality of electrode portions each extending along the first direction, and a joining portion connecting the plurality of electrode portions with each other. Moreover, when seen in a plan view, each of the plurality of electrode portions connected to the joining portion is arrayed along the second direction at a second separation distance, and the first separation distance is smaller than the second separation distance.
