摘要：
A cold cathode made of graphite is mounted at one end of a hollow tubular member. Concavities and convexities are formed on the surface of the cold cathode facing a center side of the tubular member. A fluorescent film is formed on the inner circumferential surface of the tubular member. An electron lead electrode for generating an electric field for pulling out electrons from the cold cathode is mounted on the tubular member. A fluorescent lamp is provided which uses the cold cathode capable of realizing good electron emission characteristics without an issue of tight adhesion between the cold cathode and a support substrate.
