To provide a lighting system utilizing discharge plasma that emits light in all directions, easy to achieve a predetermined spacing between a wire material and a fluorescent material, and excellent in productivity.

The lighting system comprises: a metal rod 11; a fluorescent material 12 formed in the shape of a cylinder around the metal rod 11; a wire material 13 provided around the fluorescent material 12 with a predetermined spacing between itself and the fluorescent material surface and with a carbon film formed on the entire perimeter thereof; and a vacuum sealing body 10 in which the metal rod 11, the fluorescent material 12 and the wire material 13 are enclosed. By applying a voltage between the metal rod 11 and the wire material 13, electrons emitted from the wire material 13 collide with the fluorescent material 12 to cause light emission.
