Abstract:
1. An electron beam apparatus comprising: a rear plate having a plurality of electron-emitting devices each provided with a device electrode, and a plurality of wirings connected to the device electrodes; and a face plate being provided with an anode electrode, and being arranged in opposition to the rear plate so as to be irradiated with an electron emitted from at least one of the electron-emitting devices, wherein for each device electrode the device electrode is electrically connected to the wiring through an additional electrode, and the additional electrode is formed from an electroconductive material of which phase transition from a solid phase directly into a vapor phase is caused at a temperature not lower than a melting point of the device electrode within an evacuated atmosphere, the device electrode has a high temperature portion of which temperature increases locally at a time of flowing current therethrough, and a distance L
