Abstract
An electron gun supporting member includes an insulating supporting member configured such that its one end is connected to a predetermined member having a ground potential and other end is connected to a high-voltage electrode to which a high potential being a negative high potential for emitting electrons from an electron source is applied, so as to support the high-voltage electrode, and a metal film formed in a partial region, which contacts neither the high-voltage electrode nor the predetermined member, on the outer surface of the insulating supporting member.
