Abstract

In this ion generation apparatus, tip end portions of needle electrodes are aligned in an X direction with being oriented in a Z direction, and protrude from a casing. A protective cover covers the tip end portions of the needle electrodes. The protective cover is provided with holes opened to allow tip ends of the needle electrodes to be seen from the Z direction, and an opening opened to allow the needle electrodes to be seen from a Y direction. Therefore, ions generated at the tip end portions of the needle electrodes can be emitted efficiently out of the casing. Further, a user can be prevented from touching the tip end portion of the needle electrode and injuring his or her finger or the like.
