To collet even fine dust through a dust collecting filter.

This vacuum cleaner is constituted of an air blowing means 6 for fetching the dust or the like on a floor surface to a dust collecting part 14 inside a vacuum cleaner main body 1, at least one cathode 18 for ionizing the dust fetched to the dust collecting part 14 and at least one anode 19 for sucking the ionized dust. Thus, the fine dust ionized by the cathode 18 is sucked to the anode 19 and collected. Also, since air is blown and the dust is fetched to the vacuum cleaner main body 1, the motor-driven fan of small capacity is used for the air blowing means 6 and thus, noise and power consumption are reduced, miniaturization is performed and a weight is reduced.
