Abstract

PURPOSE:To prevent separation of the inner conductive film and improve withstand-voltage characteristic by applying insulating material to the area making contact with the neck part of a spacer. CONSTITUTION:A spacer 23 is constituted in such a way that the spacer curved part 32 made of insulating material such as ceramic of glass is mounted through caulking onto the top end of a spacer holder 31 made of metal such as stainless steel or inconel. As the part making contact with the neck of the spacer 23 is made of insulating material, a concentrated electric field is not generated at the contact between the spacer 23 and the inner wall of the neck, even if high voltage is applied, and the generation of crack on the glass at the contact can be prevented.
