るコロナ放電器。 A corona discharger comprising a discharge wire stretched between a pair of insulator blocks made of resin, a conductive metal fitting having at least one end embedded and held in the insulator block, and one embedded end of the conductive metal fitting. and a screw member that forms a conduction path from the insulator block to an end on the high voltage power supply side outside the insulator block, and a blank hole having a diameter smaller than the outer diameter of the screw member is bored in one end of the conduction fitting. A corona discharger characterized in that the screw member is screwed into the blank hole while carving a thread groove so that the conductive metal fitting and the screw member are electrically connected.
