Abstract
A fluorescent lamp lighting device includes a fluorescent light bulb having an electrode filament and an electronic lighting circuit substrate for lighting the fluorescent light bulb, wherein a capacitor connected in parallel with the fluorescent light bulb, a positive characteristic thermistor connected in parallel with the capacitor, and a negative characteristic thermistor connected in parallel with the electrode filament are mounted on the electronic lighting circuit substrate, and wherein the negative characteristic thermistor, having a mounting surface, is mounted in such a manner that the mounting surface is in abutment with the electronic lighting circuit substrate. The positive characteristic thermistor and the negative characteristic thermistor are preferably mounted on mutually different mounting surfaces among the two mounting surfaces of the obverse and reverse surfaces of the electronic lighting circuit substrate.
