Abstract: PROBLEM TO BE SOLVED: To almost equalize discharge voltages with respective anodes by arranging communicating holes of a shielding plate in a position where dispersion of respective discharge passage lengths between the respective anodes and a cathode can be reduced as much as possible. SOLUTION: In a belly part 20c of a shielding plate 20, communicating holes 21a and 21b penetrating in the plate thickness direction are protrusively arranged in almost equal distance positions to the lateral both sides from the center of a cathode 7, and discharge generated between respective anodes 11 and the cathode 7 is passed through into the respective communicating holes 21a and 21b. When starting voltage is impressed between the respective anodes 11 and the cathode 7, discharge is generated, and this discharge passes through into the closest communicating hole 21a or 21b of the shielding plate 20.  In this case, since the communicating holes 21a and 21b are arranged in a position where dispersion of respective discharge passage lengths between the respective anodes 11 and the cathode 7 can be reduced as much as possible and can be equalized, the dispersion of the respective discharge passage lengths between the respective anodes 11 and the cathode 7 can be reduced and equalized. Therefore, starting voltages with respective anodes 11 and lamp voltages after starting can be almost equalized.
