PROBLEM TO BE SOLVED: To provide a ballast capable of being miniaturized and reduced in weight and thickness at a low cost. SOLUTION: A hybrid IC(HIC) 100 is arranged on the bottom part of a metal case 20, and a resin case 21 is received in the metal case 20 with a transformer 41, an inductor 31, a transformer 71, a capacitor 45 and the like disposed in the resin case 21 provided with terminals 24a, 24b. At that time, the transformer 41, the inductor 31, the transformer 71 and the capacitor 45 are disposed outside the circumferential part of the HIC 100. Thereby, this discharge lamp device can be thinned by a portion where the HIC 100 does not overlap the transformer 41 and the like. |
