Abstract
An ion generator includes: an arc chamber; a repeller that includes a repeller plate provided within the arc chamber and a repeller extension portion inserted through a through hole communicating the inside and the outside of the arc chamber; and a supporting structure that is provided outside the arc chamber and that supports the repeller so that a gap is ensured between the repeller extension portion and an inner wall of the through hole. The supporting structure includes a cover member that forms, outside the arc chamber, a small chamber communicating with the gap, and an insulation member that electrically insulates the arc chamber and the repeller from each other.
