Abstract

PURPOSE:To keep the resistance value of a high-resistance film at a given value by forming a high resistance film-provided area in a funnel portion into an uneven surface of a serrated cross section and also forming the surface of the high resistance film into a zig-zag shape. CONSTITUTION:The high resistance film-provided area 19 in a funnel portion 2' has an uneven surface with a serrated tube-axlewise cross section and a high resistance film 5' provided in the area 19 has a zig-zagged cross section along the uneven surface. Thus, no short-circuit by getter deposited film takes place in the high resistance film 5' even when a conductive getter substance is adhered to the surface of the high resistance film 5' because of the zig-zagged surface of the film 5'.
