Abstract
There is provided an airflow generation device and the like capable of suppressing an increase in a number of poles of a slip ring, and effectively preventing a malfunction from occurring due to a generation of noise caused by the slip ring. An airflow generation device of an embodiment has a main body, a rotation speed detecting unit, and a voltage application unit. The main body has a first electrode and a second electrode provided to a base formed of a dielectric, and is disposed on a rotary body. The rotation speed detecting unit detects a rotation speed of the rotary body. The voltage application unit generates an airflow by applying a voltage between the first electrode and the second electrode based on the rotation speed detected in the rotation speed detecting unit. Here, the voltage application unit and the rotation speed detecting unit are disposed in the rotary body.
