摘要：
A self-ballasted fluorescent lamp 50 includes a fluorescent lamp 1 and a ballast circuit 2 for operating the fluorescent lamp. The ballast circuit 2 includes: a printed circuit board 6; a heat generating component 7 disposed on a first face 6a of the printed circuit board, which generates heat when the fluorescent lamp 1 is operated; and a semiconductor component 17 disposed on a second face 6b opposite to the first face 6a of the printed circuit board 6, and wherein the semiconductor component 17 is disposed in an area other than an area on the second face 6b corresponding to an area of the first face 6a where the heat generating component 7 is disposed.
