An atomizing member that includes a piezoelectric vibrator and a vibrating membrane. The piezoelectric vibrator includes a cylindrical piezoelectric body, a first electrode disposed on an inner circumferential surface of the piezoelectric body, and a second electrode disposed on an outer circumferential surface of the piezoelectric body. The piezoelectric vibrator performs cylindrical breathing vibration. The vibrating membrane is disposed on an opening at a first side in an axial direction of the piezoelectric body so as to cover the opening. The vibrating membrane has a through hole in its central portion.
