An electrostatic speaker capable of relaxing a restriction on the allowable amplitude of a diaphragm while maintaining the linearity of a force acting on the diaphragm. The electrostatic speaker mainly includes electrodes opposed to each other, a diaphragm, and elastic members interposed between the diaphragm and the electrodes. The elastic members have an elastic characteristic that generates a restorative force corresponding to higher order terms of an electrostatic force generated by the electrodes and acting on the diaphragm.
