To provide an atomizing device which has a high atomizing efficiency and can be produced easily.

The atomizing device 1 includes: a cylindrical piezoelectric body 5; and a first electrode 6 and a second electrode 7 formed on the outer peripheral surface of the piezoelectric body 5. Further, the device has a constitution provided with a piezoelectric oscillator 4 which performs cylindrical breathing vibration, and a vibrating body 8 formed with a plurality of through-holes 10a at one end of an opening section in an axial direction of a piezoelectric body 5 in the center in a manner covering the opening section.
