<p>PURPOSE:To attain high collecting efficiency at a low voltage, to eliminate the fear of firing at the time of using and the fear of disconnection even in applying folding working such as pleating. CONSTITUTION:In this charging filter having a linear or belt like electrode 2 provided on the surface of a filter medium 1 and using an electrode provided on one surface of the filter medium 1 as a high voltage electrode and an electrode provided on another surface of the filter medium 1 as an earth electrode, at least one of the high voltage electrode and the earthed electrode is formed from a sheet base material obtained by sticking electroconductive short fibers to an electroconductive film.</p> |
