DETECTION APPARATUS

A detection apparatus is provided including a touch detection surface serving as a detection region having two dimensions; and first electrode components including divided electrodes arranged in the touch detection surface, first connection lines connected to one of the divided electrodes on a one-to-one basis, and a detection unit configured to output a detection signal to the divided electrodes via the first connection lines, wherein the first connection lines has a first switch between a corresponding one of the divided electrodes and the detection unit, in each of the first electrode components, the first connection lines are connected to each other between the first switches and the detection unit, and in each of the first electrode components, the divided electrodes function as one first electrode when all the first switches are closed.
