。An electrode having a planar through hole is provided on one surface of the zinc oxide varistor element, and the tip of a metal rod, which is biased in the direction of separation by a spring, is bonded to the hole with a low melting point alloy, and the temperature of the varistor element is adjusted. In a lightning arrester equipped with a mechanism that melts the low melting point alloy at the joint and separates the electrode and the metal rod when the voltage increases due to leakage current, etc., the end of the metal rod inserted into the through hole of the electrode is A recess is provided on the outer periphery,
- An opening mechanism for a lightning arrester, characterized in that a low melting point alloy is filled between the recess and the through hole and a metal rod is joined to the electrode.
