摘要

PROBLEM TO BE SOLVED: To form a surface conduction type electron discharge element having large area easily at low cost. ;SOLUTION: An ink jet unit 10 for imparting at least one droplet of solution to a predetermined part on the surface of a material to be processed is provided with a local heating mechanism 11 for drying and solidifying the droplet 12. A thin conductive film 15 communicating a pair of element electrodes 2, 3 on a substrate 1 is formed using the ink jet unit and an electron discharge part is formed at a part thereof thus producing a surface conduction type electron discharge element.;COPYRIGHT: (C)1997,JPO
