Abstract
In a color cathode ray tube, an electron gun assembly is received in a neck and includes three cathode electrodes, which are heated by heaters, respectively, and a plurality of electrodes. A sealing portion is welded to a stem section of the neck, and stem pins holding the electron gun are buried in the sealing portion. A wire is connected at one end to the stem pin and also connected at the other end to the electrode corresponding to the stem pin so as to electrically connect the electrode to the stem pin. The wire is provided with a folded portion. Even if the wire is thermally expanded, the thermal expansion is absorbed by the folded portion so as to suppress the fluctuation of the cathode current flowing into the electrode.
