摘要：
To provide a cold cathode element, which has a high practicability and is capable of emitting electrons sufficiently even at a low voltage applied. The cold cathode element emits electrons by application of an electric field to the element and is formed of an amorphous carbon film, the refractive index n of a surface of the film being equal to or larger than 2.5.
