PROBLEM TO BE SOLVED: To provide an electrostatic speaker that vibrates the entire diaphragm while reducing displacement of the diaphragm. SOLUTION: An elastic member 30U is placed on an upper surface of the diaphragm 10, and an upper surface of an elastic member 30L is bonded to a lower surface of the elastic member 30U by using an adhesive 40 applied in a through hole 11, to integrate the elastic members 30U and 30L. In this case, a gap is formed between the adhesive 40 and the diaphragm 10, and thus, the diaphragm 10 can be freely displaced in left and right directions or a depth direction within a range of the through hole 11. Also, since no adhesive 40 is applied to the diaphragm 10, and the diaphragm 10 is not bonded to the elastic members 30U and 30L, the displacement of the diaphragm 10 is not restricted anywhere in the vertical direction for the elastic members 30U, 30L, and the whole surface can be vertically displaced.
