Abstract
A detection apparatus is provided and includes touch detection surface serving as detection region having two dimensions; first electrodes arranged in first and second directions in the two dimensions; and connection lines connected to first electrodes in one-to-one manner and connected to signal output unit, base electrode opposed to first electrodes with predetermined gap there between, electrode driver configured to provide drive signal and force signal to first electrodes, wherein signal output unit is configured to output first signal indicating position where touch operation has been performed when drive signal is provided to first electrodes, first signal being represented by self-capacitances of first electrodes, and to output second signal indicating force that is applied to detection region when force signal is provided to first electrodes and that brings first electrodes close to base electrode, second signal is signal based on electrostatic capacitances obtained by individual detection, and individual detection is such that detection of each of the electrostatic capacitances between base electrode and first electrodes is individually performed.
