Summary:PROBLEM TO BE SOLVED: To provide a cathode-ray tube that can keep insulation between a plurality of interior electroconductive films impressed with anode potentials and that can retain vacuum within the tube. SOLUTION: A cathode-ray tube body 2 has a plurality of interior conductive films 11 and 12, on the inner wall of funnel 2b, to which different anode potentials HV1 and HV2 are impressed. The cathode-ray tube 1 is painted with a high resistor 13 between these plural interior conductive films, and a ridge 14 or a groove is provided on the inner wall of funnel 2b of the cathode-ray tube body 2 at the portion where the resistor 13 is painted.
