A small and inexpensive plasma actuator is capable of accelerating induced flow and increasing the effect of controlling flow. A plurality of electrode pairs are disposed on a dielectric layer upstream to downstream along a predetermined direction. Each electrode pair includes an upstream electrode disposed on one surface of the dielectric layer and a downstream electrode disposed on another surface of the dielectric layer to sandwich the dielectric layer between the upstream electrode. A lowest electrode is on the one surface of the dielectric layer displaced downstream from the downstream electrode in an the most downstream electrode pair to have the same potential as the downstream electrode. A voltage application device is configured to apply voltage including AC voltage or repeated pulse voltage to each electrode pair such that the potential of the applied voltage inverts at adjacent electrode pairs.
