Abstract: The metal halide lamp with a ceramic discharge vessel (4) has sealing means at its two ends (6), an electrically conductive lead-through (9, 10; 30) being guided through these means in a vacuum-tight manner, to which lead-through an electrode (14) with a shank (15) is attached, which electrode projects into the interior of the discharge vessel. At least a front part, which faces toward the discharge, is designed as a component made from electrically conductive cermet which comprises a halide-resistant metallic phase and a ceramic phase of a ceramic base material. The fill comprises at least one halide of a rare-earth metal. At least on the front side of the component, at least part of the ceramic phase comprises the combination of the ceramic base material and one or more rare-earth metal oxides.
