Abstract
In an ion generation apparatus, an induction electrode for generating positive ions and an induction electrode for generating negative ions are each formed as an independent part and separately mounted on a substrate. Therefore, even if the substrate is warped with changes in temperature, tip end portions of needle electrodes can be positioned at the centers of through holes in the induction electrodes, respectively, and positive ions and negative ions can be stably generated.
Claims5
An ion generation apparatus, comprising:
- a first induction electrode having a first hole;
- a second induction electrode having a second hole;
- a first needle electrode having a tip end placed at a central portion of said first hole for generating positive ions;
- a second needle electrode having a tip end placed at a central portion of said second hole for generating negative ions;
- and
- a substrate mounted with said first and second induction electrodes and said first and second needle electrodes,
- said first and second induction electrodes each being formed as an independent part and mounted separately on said substrate.
