Abstract
An electrostatic coordinate input device includes a finger detection unit that detects a proximity position of a finger of an operator on an operation surface by a capacitive sensing method; and a correction unit that, in a case where two proximity positions corresponding to two fingers are detected by the finger detection unit, corrects the two proximity positions so as to increase a distance between the two proximity positions.
