<p>PROBLEM TO BE SOLVED: To provide a manufacturing method of an electron source which can form in a given thickness a conductive film of high resistance set for eliminating problems due to abnormal discharge phenomenon or the like, even in case there exists a porous member on a substance and, especially, can form a uniform conductive film by a spray coating method advantageous in cost. SOLUTION: In forming a conductive film 6 for an electron source provided with a plurality of electron emission elements, a plurality of wires for driving them, an insulating body 81 for insulating between the wires, and the conductive film 6 covering at least the insulating body 81, before a process of furnishing a composite including a conductor that is a component material for the conductive film and liquid medium at least on the surface of the insulating body 81, solution with all or part of the liquid medium as an ingredient is furnished at least on the surface of the insulating body.</p> |
