Abstract: <P>PROBLEM TO BE SOLVED: To provide an electron emitter capable of emitting electrons with low power.  <P>SOLUTION: This electron emission source 20 is formed into an acute shape, and a hafnium carbide thin film 22 is formed on an electron emission part 23 formed of the tip of the source.
