<p>PURPOSE:To reduce the size and weight of the air cleaner body and to provide the inexpensive air cleaner having high reliability by forming a discharge electrode part to a small size. CONSTITUTION:This air cleaner is constituted by constituting a discharge device part 33 of a flat planar grounding electrode 31 and needle-like discharge electrodes 30 disposed to face this flat planar grounding electrode 31, providing the needle-like discharge electrodes 30 at one end of a resistor 39 disposed on an insulating sheet 3, connecting the other end of the resistor 39 to a winding core conductor 40 to constitute the winding core thereof, winding the insulating sheet 38 around the winding core conductor 40, projecting the needle-like discharge electrode 30 parts from the winding part and applying a high voltage between the flat planar grounding electrode 31 and the winding core conductor 40.</p> |
