Abstract
A dust collection device can be fitted to windows in a room, thus not only cleaning air while ventilating air within a space targeted for cleaning but also cleaning air outside of the space. A dust collection device is constructed by laminating first insulation type electrodes and second insulation type electrodes alternately via spacers. The insulation type electrodes have a configuration in which both sides of first electrodes (second electrodes) are coated by first insulating layers (second insulating layers). Furthermore, a power supply is connected to the electrodes, and the electrodes are grounded. In addition, a plurality of first through holes (second through holes) is provided in rows in the insulation type electrodes. Furthermore, the positions of the through holes in the insulation type electrodes are arranged in a plane view so as to be a prescribed distance from the positions of the through holes in the insulation type electrodes.
