PROBLEM TO BE SOLVED: To allow uniform light emission by suppressing light emission flicker of a phosphor, to enhance emission efficiency by improving luminance, to suppress rise of a tube surface temperature, and to facilitate manufacturing. SOLUTION: In this field emission lamp 10, a positive electrode 18 with a phosphor 16 is arranged in a planar form oppositely to a field electron emitter 20. In the field emission lamp, the phosphor 16 emits light by being irradiated with electrons emitted from the field electron emitter 20. The field emission lamp is structured such that a secondary electron emitter 26 multiplying and generating secondary electrons from the electrons emitted from the field electron emitter 20 to emit them to the positive electrode 18 is arranged between the field electron emitter 20 and the positive electrode 18.
