PURPOSE: To accomplish an electrostatic relay of such a structure that its possibility of practical application is not, impaired even in the single mode and that it is easy to secure a requisite and sufficient electrostatic power when a driving voltage is impressed.
CONSTITUTION: An electrostatic relay concerned is equipped with a stationary side base 2, which has a stationary contact 21 and a stationary side driving electrode 11, and a movable plate 13 having a movable contact 22 and a movable side driving electrode, wherein such an arrangement is introduced that see-saw motions are possible in the condition the movable plate 13 confronts the stationary side base 2. The movable contact 22 is positioned facing the stationary contact 21 at least on one side viewed from the fulcrum P of the see-saw motions, and the stationary side driving electrode 11 and movable side driving electrode confront on the two sides of the fulcrum P, and at either of these two electrodes, an electret 9 is installed for drawing one side of the movable plate 13 to the stationary side when the driving voltage is out of impression. Thus the see-saw motions are generated in the movable plate 13, wherein the other side of the movable plate 13 is drawn to the stationary side while the driving voltage is impressed on the driving electrodes.
