Abstract
The position detection device includes a detector that detects degrees of contact or degrees of proximity of an object to an operation surface at a plurality of detection positions on the operation surface and outputs a plurality of detection data representing the degrees at the plurality of detection positions, a coordinate calculator for calculating a spatial coordinate of the object in a spatial coordinate system having a first axis and a second axis included in a plane parallel to the operation surface and a third axis, based on the plurality of detection data detected by the detector, and a coordinate corrector that corrects a coordinate value of the first axis or a coordinate value of the second axis in the spatial coordinate based on a coordinate value of the third axis in the spatial coordinate calculated by the coordinate calculator.
