PURPOSE:To prevent sticking of moisture and to obviate the change in electric discharge characteristics according to environments by forming either one of electrodes for excitation and discharge of a flat type electric discharger of a resistor for the purpose of heating and applying an electric power source for heating. CONSTITUTION:With an insulator 2 of glass or the like in-between, an exciting electrode 1 formed of a resistor is provided by facing electric discharge electrodes 3 of a rectangular strip shape. An electric power source 5 for heating is also applied to the electrode 1 other than an electric power source 4 for driving, by which the electrode 1 is heated to remove moisture satisfactorily. Thus the sticking of moisture upon the insulator 2, etc. is prevented and the change in discharge characteristics according to environmemts is obviated. |
