ABSTRACT:
An object of the present invention is to provide, without increasing the costs or decreasing the quantity of light, a fluorescent lamp that is less likely to have the bridge and the constituent tubes damaged while being handled and has improved handleability, as well as to provide a manufacturing method therefor. It is arranged so that the distance between the first and second constituent tubes gradually becomes smaller from the base side of the lamp toward the turning portion side of the lamp where the discharge paths turn. It is arranged so that the value of D2/D1is within a range of 0.05 to 0.70 inclusive, where D1is the distance between the first and second constituent tubes being measured at the bridge connecting points on the base side, and D2is the shortest distance between the first and second constituent tubes on the turning portion side.
