PROBLEM TO BE SOLVED: To provide an ion filter 10 used in an electronic amplifier 100.SOLUTION: An ion filter includes: an insulating base material 11; a first conductive layer 12 formed on one main surface of the insulating base material 11; a second conductive layer 13 formed on the other main surface of the insulating base material 11; and a plurality of through holes 30 formed along a thickness direction of the insulating base material 11. In the ion filter, the first thickness th1 of the first conductive layer 12 is different from the second thickness th2 of the second conductive layer 13.SELECTED DRAWING: Figure 2C |
