The electron gun also includes a voltage-dividing resistor for producing a voltage applied to a first focus electrode by dividing a voltage applied to the anode, and a metal conductor surrounding the resistor and fixed to a second focus electrode upstream of the first focus electrode. The resistor is disposed in the vicinity of one of the support rods, is formed of an insulating film, a resistance pattern, and a substrate disposed in the order named from the insulating film toward the neck portion. The resistance pattern is such that a potential difference between the metal conductor and a portion of the resistance pattern facing the metal conductor is equal to or smaller than 4 kV.

摘要： A heat generating portion of a heater which is incorporated in an indirectly heated cathode structure of an electron gun for a cathode ray tube is formed by joining a first winding portion and a second winding portion which differ in the number of coil winding layers and by twisting and winding a joined body in a double helical structure. The present invention allows a cathode temperature to have a high temperature and hence, it is possible to enhance the electron irradiation characteristics even when a degree of in-tube vacuum is lowered.
