An electron beam generator device includes a base body having a conductive surface and a electron-emission electrode having a carbon nanotube structure on the conductive surface of the substrate. The carbon nanotube structure constitutes a network structure which has plural carbon nanotubes and a crosslinked part including a chemical bond of plural functional groups. The chemical bond connects one end of one of the carbon nanotubes to another one of the carbon nanotubes. A method for producing an electron beam generator device, includes applying plural carbon nanotubes each having a functional group onto a conductive surface of a base body, and crosslinking the functional groups with a chemical bond to form a crosslinked part, thereby forming a carbon nanotube structure constituting a network structure having plural carbon nanotubes electrically connected to each other.
