1. A detection device comprising:
a first electrode extending in a first direction along a detection face;
a plurality of second electrodes extending in a second direction that crosses the first direction along the detection face, and facing the first electrode;
a signal output circuit configured to output a signal to the first electrode;
a detection circuit configured to detect capacitance generated between the first electrode and the second electrodes in accordance with the signal; and
a force-sensing element configured to detect force applied to the detection face,
wherein a plurality of first electrode blocks each including a plurality of the first electrodes are arranged in the second direction, and
wherein the signal output circuit is provided to be switched between a first mode of outputting the signal to the first electrode blocks at different times and a second mode of outputting the signal to some of the first electrodes and is configured to start operation on the second mode when the force is detected.
