<p>In this ion generator, induction electrodes (3, 4) are formed on the surface of a first printed circuit board (5), holes (5a, 5b) are made on the inner side of the induction electrodes (3, 4), needle electrodes (1, 2) are mounted on a second printed circuit board (6), and the tips of the needle electrodes (1, 2) are inserted through the holes (5a, 5b). Consequently, current can be prevented from leaking between the needle electrodes (1, 2) and the induction electrodes (3, 4) even when placed in a high-humidity environment in a state in which dust has accumulated on the first and second print boards (5, 6).</p> |
