Abstract
In a color cathode ray tube, inner lead pin segments which extend inside the neck of a funnel constituting an vacuum envelope, outer lead pin segments which are led out of the neck and interconnecting wires which respectively connect both lead pin segments together are provided in a stem for sealing the end portion of the neck. The inner lead pin segments are arranged along a first circumference and are supported by respective projections protruding from the stem. The outer lead pin segments are arranged along a second circumference having a larger diameter than that of the first circumference. The inner lead pin segments are connected to the respective outer lead pin segments by the respective interconnecting wires which are bent in the stem and the respective projections.
