Abstract
A method of manufacturing a resistor element, particularly one for use as an arc suppressing resistor in a cathode ray tube which consists in providing an arc suppressing resistor having a resistor core of predetermined resistance covered with an integral ceramic insulating layer, and baking the resistor in a vacuum atmosphere at a vacuum ranging from 1.times.10.sup.-3 Torr to 1.times.10.sup.-7 Torr, a temperature from 250.degree. to 500.degree. C. and a treatment time or more than 30 minutes.
