An electron beam device having an airtight container, an electron source provided in the container and a spacer (1), characterized in that the spacer (1) has at least an area (4) where a fine particle-containing layer exists, a sheet resistance of the spacer as measured on the surface of the area is 10<7> OMEGA /c or higher, and the fine particles have an average grain size of up to 1000 ANGSTROM and contain at least metal elements. The electron beam device delivers an excellent display quality minimized in luminous point displacement and in creeping discharge, and an extended reliability.
