Abstract
Respective first end portions of first and second internal electrodes are exposed at respective end surfaces of a varistor body, which is in the form of a rectangular parallelepiped. These end surfaces of the varistor body are covered with low resistance parts which include ceramic material in order to prevent the internal electrodes from decomposition. External electrodes are formed on the low resistance parts, so as, to be electrically connected with corresponding ones of the internal electrodes through the low resistance parts.
