In a colour cathode-ray tube having a focusing electrode applied with the focusing voltage and an anode electrode applied with the anode voltage, there is provided an intermediate electrode which is applied, through an incorporated dividing resistor (301), with a potential which is higher than the focusing voltage and lower than the anode voltage. Metal bodies (63A,B) are wound around the electron gun, each metal body being spaced by a respective distance from the inner wall of the neck of the cathode ray tube. The incorporated dividing resistor (301) has reduced length or has a width-constricted portion so as to enable the metal bodies (63A,B) to be wound around the electron gun in a symmetrical fashion thus rendering substantially equal the respective distances between each of the metal bodies (63A,B) and the inner wall of the neck of the cathode ray tube.
