PROBLEM TO BE SOLVED: To provide a lighting device for an electrodeless discharge lamp, which can prevent high-frequency noise generated in a high-frequency power circuit from being superimposed on a control signal wire leaded out with certainty and ease. SOLUTION: A printed substrate 26, on which a high-frequency power circuit 4 which supplies a high-frequency power to a high-frequency power supply coil for lighting an electrodeless discharge lamp is mounted, is contained in a shield case 25, a control signal wire 16 electrically connected to the high-frequency power circuit 4 for controlling the high-frequency power outputted from the high-frequency power circuit 4 is provided, and a wiring pattern 18 is formed on the printed substrate 26 so as to be interposed between the high-frequency power circuit 4 and the control signal wire 16 and come close to the shield case 25. |
