ELECTRON EMISSION MEMBER, ELECTRON EMITTING DEVICE, AND METHOD OF MANUFACTURING ELECTRON EMISSION MEMBER

摘要

PROBLEM TO BE SOLVED: To provide an electron emission member and an electron emitting device which have excellent electron emission characteristics, and a method of manufacturing the electron emission member.

SOLUTION: The electron emission member is an extruded material b having a carbon nanofiber dispersed in a metal matrix. A surface formed in a direction crossing an extrusion direction A for the extruded material b is an electron emission area. The method of manufacturing the electron emission member includes a step (a) of by extruding a mixed material B containing metal particles and a carbon nanofiber to acquire the extruded material b, and a step (b) of dividing the extruded material b at a plurality of location at least in the extrusion direction A to acquire the electron emission member having divided surfaces formed in the direction crossing the extrusion direction A.
