Atomizing member and atomizer including the same

An atomizer comprising:

• an atomizing member including:
• a piezoelectric vibrator that 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 and configured to perform cylindrical breathing vibration, and
• a vibrating membrane disposed on an opening of the piezoelectric body at a first side in an axial direction thereof so as to cover the opening, the vibrating membrane having a through hole in a central portion thereof;
• an atomizer main body on which the piezoelectric vibrator is mounted, the atomizer main body including a storage for storing liquid;
• and
• a liquid feeder that supplies the liquid stored in the storage to the section of the vibrating membrane where the through hole is disposed,
• wherein the piezoelectric vibrator includes a flange connected to a section of the piezoelectric body at the first side in the axial direction thereof, the flange extending outwardly in a diametrical direction from the section at the first side, the flange including a peripheral portion in the diametrical direction supported by the atomizer main body,
• wherein the flange also including at least two bridges formed by a plurality of through holes extending in a circumferential direction thereof, the at least two bridges connecting the peripheral portion and the vibrating membrane, and
• wherein a length of each of the at least two bridges is within a range of 30% to 50%, 70% to 90%, or 115% to 120% of a radius of the vibrating membrane.
