A hand dryer is equipped with a hand insertion area (10), having a width that is able to accommodate hands, a high-pressure air generator (2), which generates a high-pressure airflow, discharge nozzles (N1, N2), which are disposed in the upper surface of the hand insertion area (10) and blow the high-pressure airflow, an exhaust duct (4), which is connected between the exhaust side of the high-pressure air generator (2) and the discharge nozzles (N1, N2), an ejection port (23), which opens to the space surrounding the hand dryer, a switching damper (24), which opens a portion of the exhaust duct (4) and is connected to the ejection port (23), and an ion generator (22), which generates ions having sterilization action into the high-pressure airflow passing through the exhaust duct (4) on the upstream side of the switching damper (24).
