    Abstract: An electron gun cathode (104) is column shaped, and emits electrons by being heated. A holder (103), which covers the bottom and sides of the electron gun cathode, has electrical conductivity and holds the electron gun cathode, and is composed of a material that does not easily react with the electron gun cathode when in a heated state, is provided. The tip of the electron gun cathode (104) protrudes from the holder (103) so as to be exposed, and electrons are emitted from the tip toward the front by applying an electric field to the tip.

    Abstract: Provided is an electron source which provides a stable electron beam even when vibration is applied from external to a device which uses the electron source. The electron source is provided with a needlelike chip (1) having an electron emitting section at one end; a cup-like component (6) bonded to the other end of the needlelike chip (1); and a filament (3) for heating the cup-like component (6). The filament (3) is arranged in a gap inside the cup-like component (6), in a noncontact state to the cup-like component (6).
