| 摘要 |
This ion filter is configured to comprise an insulating base (11), a first conductive layer (12) that is formed on one main surface of the insulating base (11), a second conductive layer (13) that is formed on the other main surface of the insulating base (11), and a plurality of through holes (30) that are formed in the thickness direction of the insulating base (11). This ion filter is also configured such that the first thickness (th1) of the first conductive layer (12) and the second thickness (th2) of the second conductive layer (13) are different from each other. |
