The touch detection unit includes: first electrodes extending along a first direction; and a first signal output unit configured to output a first signal indicating a position of the touch operation in a second direction. Each first electrode includes divided electrodes provided in the first direction. First detection regions each provided by bundling the divided electrodes arranged in the second direction are set. The force detection unit includes a base electrode configured such that distances between the base electrode and the respective divided electrodes change when the first electrodes bend according to the applied force applied.
