An air conditioner is provided that includes a dust collecting filter assembly that collects foreign substances from air suctioned in through an inlet. The dust collecting filter assembly includes a high-voltage electrode film, a ground electrode film disposed parallel to face the high-voltage electrode film, a separator film disposed between the high-voltage electrode film and the ground electrode film so that the high-voltage electrode film and the ground electrode film are spaced apart by a predetermined interval, and a fastener that fastens the high-voltage electrode film, the ground electrode film, and the separator film together to integrate them.
