PROBLEM TO BE SOLVED: To provide an air current generating device which can accelerate a flow rate of a generated induced flow while suppressing a voltage to be applied to a pair of electrodes which generates dielectric barrier discharge.SOLUTION: An air current generating device 10 includes: a dielectric body 20; a first electrode 21 provided on a surface 20a of the dielectric body 20; a second electrode 22 provided, via a dielectric body F, at a position away from the surface 20a of dielectric 20 more than the first electrode 21 and also a position shifted from the first electrode 21 in a direction an inductive flow F flows; and a third electrode 23 provided, via the dielectric body 20, at a position shifted from the second electrode 22 in the direction the inductive flow F flows and on the surface 20a of the dielectric body 20. A discharge power supply 40 that applies an alternating voltage between the first electrode 21 and the second electrode 22, and an acceleration power supply 41 that applies a voltage between the second electrode 22 and the third electrode 23 are included. The inductive flow F is generated from the first electrode side toward the third electrode side. |
