An air processing device is provided by which a current-carrying section (45) is attached to a casing (11) by an insulating member (40) having a covering section (46) covering an outer periphery face of a current-carrying section (45) and a tube-like section (41) in which a power source-side end of the covering section (46) is supported by a tube bottom section (41a). This consequently secures a long insulating distance from an electric discharge spray section (20) and a charged dust collecting section (30) via the current-carrying section (45) to the casing (11). As a result, the respective electrodes and the casing can have an improved insulating performance therebetween even under an environment where water droplets are supplied.
