This hand dryer device includes a nozzle unit including an air outlet for blowing air out in a predetermined blowing direction, a blower that supplies air to be blown out of the air outlet to the nozzle unit, a distance detection means that detects a distance between an object and the nozzle unit, the object being disposed apart from the air outlet in the blowing direction, a hand detection means that detects a hand being placed between the object and the nozzle unit, and a control unit that sets a rotational speed of the blower based on the distance detected by the distance detection means, and drives the blower when the hand detection means detects a hand. A rotational speed of the blower that is set when the distance detected by the distance detection means is less than a first distance is less than a rotational speed of the blower that is set when the distance detected by the distance detection means is equal to the first distance.
