型陰極線管。 A panel on which a phosphor stripe and an index stripe are formed up to the vicinity of the edge of the panel is insulated to a funnel equipped with an electron gun and a light-receiving element that detects the index light from the index stripe. In a beam index cathode ray tube formed by bonding with a material, there is a gap at least on the scanning start side of the bonded portion, and a conductive portion of the panel in the gap and a conductive portion formed on the inner surface of the funnel are connected to each other. Beam index type cathode ray tubes that are arranged overlappingly in the direction of the electron beam.
