Dust collecting electrode of air cleaning apparatus

PURPOSE:To solve the problem that dust collecting electrodes to be used for various kinds of air cleaning apparatuses are expensive and poor in reliability and provide dust collecting electrodes which are easy to be manufactured, economical, and sufficiently reliable. CONSTITUTION:Films 1 prepared by coating a comb-like conductive layer with an insulating film of such as a polypropylene film, etc., and comb-like conductive foils 2 are assembled to form a successively layered structure and thus provide a dust collecting electrode.
