The second housing forms, together with an actuator, a second blower chamber. A second top plate portion includes a second vent hole that allows an inside of the second blower chamber to communicate with an outside of the second blower chamber. The vibrating plate includes an opening portion and a third vent hole, the opening portion allowing an outer periphery of the first blower chamber and an outer periphery of the second blower chamber to communicate with each other.
