Abstract
A hand dryer includes: nozzles each provided on a wall of a hand insertion portion, transforming a high-pressure airflow from an air blower into a high-speed airflow, and blowing the high-speed airflow into the hand insertion portion. The hand dryer includes: a hand sensor including a plurality of electrode pairs and detecting a hand inserted into the hand insertion portion from a change in capacitance between two electrodes included in the plurality of electrode pairs, each of the plurality of electrode pairs consisting of a first electrode and a second electrode having different polarities to each other; and a controller that drives the air blower on the basis of a combination of the two electrodes with which a hand has been detected by the hand sensor.
