<p>Provided is an air processor, in which an electrically connecting part (45) is attached to a casing (11) by means of an insulation member (40) including a covering part (46) for covering the outer peripheral surface of the electrically connecting part (45) and a tubular part (41) with a tubular bottom part (41a) for supporting the power supply side-end of the covering part (46), so that the long insulation distance from a discharge spray part (20) and a charged dust collection part (30) to the casing (11) via the electrically connecting part (45) can be maintained. Consequently, the insulation performance between each electrode and the casing can be enhanced even under such a environment that water drips are supplied.</p>
