Abstract: A resistor for use in a cathode ray tube comprises an insulating plate provided thereon with at least first and second electrode terminals for use respectively with relatively high and low voltages in the cathode ray tube, a coating insulator provided on the insulating plate for covering the same, and a resistive layer provided in a predetermined pattern on the insulating plate to connect therethrough the first and second electrode terminals with each other and to be covered by the coating insulator with such an arrangement that the resistance thereof obtained per unit length on the insulating plate between the second electrode terminal and a high potential difference position between the first and second electrode terminals, where the potential difference between the outer surface of the coating insulator and the resistive layer is to be relatively large in the use of the resistor in the cathode ray tube, is greater than that between the high potential difference position and the first electrode terminal.
