摘要

An electrode (3) for igniting or monitoring a gas burner comprises a metal electrode positioned in the flame region of the burner and partly enclosed by an insulating body (4) attached to the burner. The electrode is formed of a hard, crack-resistant material (1) and a second, tough and oxidation layer-resistant material (2).
