A disk-shaped non-straight resistor II material with a diameter of 60 cm and a thickness of 810 m was prepared by heating at a temperature of 810 °C for 8 hours, and electrodes were formed using a non-straight resistor method. In the non-curved resistor manufactured in this way, the rate of change of the non-linear resistor is large when a large current pulse is applied, and therefore the non-linear resistor has a large rate of change when a large current pulse is applied. It is unsuitable for the overvoltage protection gk#L receives, and a non-IL#IIa antibody with stable electrical properties over a long period of time has been desired.
