<p><P>PROBLEM TO BE SOLVED: To provide a field emission electron source, and its manufacturing method, with heightened temperature resistance through reinforcement of intensity of a joint part of a carbon nano-material and a cathode member. <P>SOLUTION: In the method of manufacturing the field emission electron sources of a structure jointing small-gage wire members 2 made of a carbon nano-material with tips of cathode members 1, the small-gage wire members 2 are firmly fixed to the cathode members 1 by irradiating FIB of high-melting-point metal on the joint part 3 with the use of FIB 23 having as ion sources high-melting-point metal with a melting point of 1,500°C or more or its alloy. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
