Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a dust collector in which charged dust does not flow outwardly. SOLUTION: The dust collector is provided with: a discharge part 2 with a discharge electrode 21 and a counter electrode 22 for charging the dust which has passed through the discharge electrode 21 by corona discharge; a catcher part 3 for catching the dust charged in the discharge part 2; and a high voltage generation circuit 5 being switched between a positive potential and a negative potential at a prescribed time interval and applying a high voltage to the discharge part 2. As for the high voltage generation circuit 5, the switching cycle of the positive potential and the negative potential is set to be less than the time for the dust to reach the catching part 3 from the discharge part 2 when an air amount passing through the discharge part 2 is maximum and is set by a voltage for which the center value of the application voltage is a positive value. Thus, the charged dust does not easily flow outwardly. COPYRIGHT: (C)2007,JPO&INPIT
