Abstract

A discharge electrode 5 for generating ions and a high-voltage generating circuit unit 2 that supplies the discharge electrode 5 with a high voltage are housed in a housing 3 . A discharge opening 12 for discharging the generated ions is formed in the housing 3 . The housing 3 is covered by an exterior case 15 . The exterior case 15 is connected to the high-voltage generating circuit unit 2 and functions as an induction electrode. A passage opening 33 leading to the discharge opening 12 is formed in the exterior case 15 . An insulating sheet 36 covers the periphery of the passage opening 33 in the exterior case 15 facing a space into which the ions are discharged so that the discharged ions do not attach to the exterior case 15 . Decrease in the amount of discharged ions can be prevented while using a peripheral component of the discharge electrode 5 as the induction electrode.

First claim
