<p>PROBLEM TO BE SOLVED: To perform moderate discharge treatment to material to be treated before rapidly discharging it to outside a treating area in a discharge treating device for performing the discharge treatment to the material to be treated by providing a discharge hole for discharging the material to be treated that has undergone the discharge treatment in the treating area to outside the treating area in a member in the treating area. SOLUTION: When this invention is performed in a discharge treating device A1, it is provided with an electrode pair 2 and a high voltage pulse applying means 3 and between the electrode pair 2, a printed circuit board 1 is arranged. And between the electrode pair 2, pulse discharge of high voltage is generated, while crushing the printed circuit board 1 by shock waves and heat generated with it, electrically conductive parts, electronic circuit elements or the like are separated from the printed circuit board 1. At this time, as a cathodic electrode 2b being below the printed circuit board 1 of the electrode pair 2, a mesh electrode is used, and when the size of small fragments that the printed circuit board is crushed or separated becomes smaller than the mesh diameter of the mesh electrode, they are discharged from between the electrode pair 2 to prevent them from being crushed/separated too much.</p> |
