INPUT DEVICE AND INPUT SYSTEM

Provided is an input device that can offer a greater degree of flexibility in the setting of a total number of times of change in an electrical state of a fixed electrode when an operating member (20) moves from one to a next one of two click points. An input device (2) includes two fixed electrodes (29a, 29b) and an operating member (20). The two fixed electrodes (29a, 29b) is configured to be placed to overlap with specific line electrodes (Y1) of a plurality of line electrodes (Y1). The operating member (20) is movable with respect to the two fixed electrodes (29a, 29b). The operating member (20) is movable within a movable range including a plurality of click points. Electrical states (Q1, Q2) of the two fixed electrodes (29a, 29b) change among a plurality of states in accordance with a movement of the operating member 20. A divisor of an integer N does not include 4, where the integer N is a total number of times of change in the electrical states (Q1, Q2) of the at least two fixed electrodes (29a, 29b) when the operating member (20) moves from one to a next one of adj acent two click points of the plurality of click points.
