Abstract
A fixed element is provided to be used in a position detection device for detecting a position of a movable element that moves on the fixed element. The fixed element includes a substrate, a plurality of first electrodes and a second electrode. The substrate has as first surface, a second surface and a low-dielectric constant area. The second surface faces in an opposite direction to the first surface. The low-dielectric constant area has a lower-dielectric constant than other portions of the substrate. The first electrodes are disposed on the first surface of the substrate. The first electrodes include three or more phases arranged one-dimensionally in a repeating pattern in a movement direction of the movable element. The second electrode is disposed on the first surface of the substrate and is arranged in the movement direction of the movable element adjacent the first electrodes. The low-dielectric constant area of the substrate is provided in a position between the first electrodes and the second electrode.
