Abstract

PROBLEM TO BE SOLVED: To reduce the number of parts and to miniaturize a whole shape. SOLUTION: In an air cleaner unit constituted so that an ionizer unit charging particles and a dust collecting electrode unit collecting the charged particles are attached to a base and having a high voltage connection terminal applying high voltage to the ionizer unit 22 and the dust collecting electrode unit, the guide part 30 positioning the high voltage connection terminal 31 is integrated with the base. By this constitution, the guide part 30 becomes simple in constitution and the number of parts can be reduced. Since the base integrated with the guide part 30 is formed of an inorg. compd. or a material containing 20% or more talc, the tracking resistance corresponding to high voltage can be enhanced. As a result, tracking resistance several times or more as compared with that of a usual molding material is provided and safety is enhanced.
