PROBLEM TO BE SOLVED: To provide a hand dryer enabling a manager or the like to know before a blade in a high-pressure air flow generator reaches use limit.SOLUTION: A hand dryer 1 includes: a box body 2; a hand drying room 3 provided inside the box body 2 and having an opening to insert the hand into; a high-pressure air flow generator 4 provided inside the box body 2 and generating high-pressure air; a nozzle blowing out high-pressure air generated by the high-pressure air flow generator 4 into the hand drying room 3; and a control part for controlling the high-pressure air flow generator 4. The control part includes: a storage part of storing a drive frequency of the high-pressure air flow generator 4; and a determination part for determining whether a drive frequency of the high-pressure air flow generator 4, stored in the storage part reaches or not a previously set drive frequency threshold value of the high-pressure air flow generator 4. |
