PROBLEM TO BE SOLVED: To perform atomization of ion to an object to be atomized from an optimum distance at a predetermined frequency, and maintaining sterilizing, sanitizing or deodorant effect of an object to be atomized.SOLUTION: A communication part 101 receives atomization target information which specifies an atomization target object, an atomization object detection part 104 detects the atomization target object shown in the atomization target information from a space, an atomization control part 102 is means for performing ion atomizing treatment to the atomization target object at a predetermined frequency, in which the part determines a moving direction to the atomization target object detected from a present position of an ion atomizer 100, in ion atomizing treatment, and in the case where a distance between the atomization target object and the ion atomizer 100 is within a first threshold value, atomizes ion to the atomization target object, and a flight control part 106 controls flight of the ion atomizer 100 to moving direction.COPYRIGHT: (C)2016,JPO&INPIT
