<p>To provide a neutralization device having a cleaning system capable of effectively removing even membrane material adhered to an electrode needle of the device. Cleaning part 63a has polishing films 631, 632 opposing each other. End portions 6311, 6321 of the polishing films are attached to a film support 633. Each polishing film is curved so as to form a convex surface, and the polishing films are supported such that the convex surfaces of the films contact each other. Polishing films 631, 632 cooperatively form at least a portion of an opening 634 capable of receiving an electrode needle 4a, and allowing the electrode needle to pass through the opening. Opening 634 is formed by lateral portions 6312, 6322 of the opposing polishing films 631, 632 at least one lateral side thereof, which are spaced away from each other at a predetermined distance.</p> |
