Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fan that can improve safety, while maintaining user-friendliness.SOLUTION: A guard includes a fan guard that is made from a conductive material and encloses a fan, and a conductive portable holding part that is provided in the fan guard and electrically connected to the fan guard. A controller stops a motor when detecting that an object approximates to or contacts with the guard, starts to measure a time, starts to supply power to the motor when the object leaves the guard within a predetermined time, and maintains a power stopping state to the motor when the object leaves the guard after the predetermined time elapses.
