Abstract

Disclosed is an improved surface discharge element comprising a dielectric substrate having a discharge electrode on one surface and an inductive electrode on the other surface of the substrate, at least said discharge electrode being of a thick film conductor including conductive powder and lead-free glass as main constituents. The lead-free discharge electrode is physically resistive to erosion by electric discharge, and accordingly it can have an elongated life in use.
