PURPOSE:To obtain the titled structure, having good durability and useful for automotive parts, etc., by setting a laminated material having an electrically conductive member placed between undrawn PP members on a templating member having a working surface shape, decompressing and molding the material and perforating many holes for discharge. CONSTITUTION:An electrode structure for corona discharge used for treating the surface of a molded plastic article is produced. In the process, a laminated material (a') having an electrically conductive member 4' placed between undrawn decompressive polypropylene members 2' and 3' is used and set on a templating member having a working surface shape (W), decompressed and molded into a shape in conformity with the working surface shape. Many holes (1a) for discharge are then perforated on a molded article (a'') consisting of the laminated material (a') to afford the aimed electrode structure for corona discharge. |
