Abstract
A capacitive sensor includes an error compensating unit that, in an arrangement that a part of a fixed electrode as an edge portion and a part of a movable electrode as an edge portion are opposed to each other keeping a gap in a direction of shift of a detecting unit, reduces a detection error of capacitance due to the shift of comb-tooth portions from each other in the detecting unit, by a change of capacitance according to variation of the gap caused by the shift.
