ABSTRACT:
A voltage-dependent non-linear resistor member, a method for producing the same, and an arrester equipped with the same. The member is produced by a process comprising the addition of at least one oxide of a rare earth element selected from Y, Ho, Er and Yb in an amount of 0.05-1.0 mol % in terms of R.sub.2 O.sub.3 to a composition which principally consists of zinc oxide and contains bismuth oxide. The member has excellent non-linearity and a high varistor valtage. Further, the arrester has very small size and improved protective properties.
