| description | PROBLEM TO BE SOLVED: To provide a voltage non-linear resistor wherein non-linear property is excellent and high varistor voltage is obtained, a lighting arrester using the resistor and a manufacturing method of them. SOLUTION: This voltage non-linear resistor is formed by adding at least one kind of oxide of rare earth element out of Y, Ho, Er, Yb to composition wherein zinc oxide is main component and bismuth oxide is contained, with 0.5-1.0mol% reduced to R2 O3 . Then a baking process is divided into two steps. A first baking process is performed in atmosphere. In a temperature falling process of a second baking process, a gradually cooling process wherein temperature falling gradient of 0-5 deg.C/hour is set in a range between 700-400 deg.C or a temperature maintaining process keeping a constant temperature is installed, and the gradually cooling process and the temperature maintaining process are performed in atmosphere whose oxygen partial pressure is higher than or equal to 50vol.%. |
