To prevent the generation of a short circuit in a gate electrode by accurately maintaining a space between the gate electrode and an electron emitting layer.

This field emission cold cathode is provided with an insulating substrate 2, a negative electrode 3 formed on the insulating substrate 2, an electron-emitting layer 4 formed on the negative electrode 3, and a gate electrode 6 formed on the electron emitting layer 4 via the insulating material and formed of a metal thin plate formed with plural openings having a diameter at 10-100 μm. The insulating material is formed of a sintered material layer 5 of the inorganic insulating powder material formed in the surface of the gate electrode 6 counterposed to the electron-emitting layer 4, and this sintered material layer 5 is adhered to the electron-emitting layer 4.
