PURPOSE:To perform the corona discharge treatment of a three-dimensional resin molding uniformly within a short time, by generating corona discharge from a flat discharge part of a shape nearly the same as the treatment surface of the molding. CONSTITUTION:An electrode 50 for corona discharge is formed by attaching a flat discharge part 52 with its surface having grooves in the form of a lattice and having a shape nearly the same as the three-dimensional shape of the treatment surface of a three-dimensional resin molding 1 to the end of a rod-like held part 50. A counter electrode 63 is formed on the surface of a counter electrode base 62 of a shape coinciding with the shape of the back of the molding 1 and provided on an electrode mount 61, and the molding 1 is fitted on this electrode 63. The electrode is set so that the corners of the molding 1 may be opposed to the bends 52a and 52b of the discharge part 52, a high-frequency is impressed between the electrodes 50 and 63 to generate corona discharge from tetragonal prism-like protrusions 54 formed among the grooves 53 and perform the corona discharge treatment of the molding 1. |
