Abstract
A cathode ray tube includes an envelope consisting of a flat panel, a funnel and a neck. The flat panel has a phosphor layer and a conductive layer respectively coated on its inner surface and the funnel is provided with an anode button. An anode contactor is attached to the anode button at its inner end. In this case, the anode contactor consists of a base portion made of a flat plate and extended substantially along the inner surface of the funnel and a leaf contactor integrally extended from the base portion so as to resiliently contact with the conductive layer coated on the inner surface of the flat panel. The base portion of the anode contactor is provided with a projection near a portion from which the leaf contactor is extended, the projection contacting with the inner surface of the funnel, and provided with an insertion aperture at a portion opposite to the portion from which the leaf conductor is extended, the inner end of said anode button engaging with said insertion aperture.
