It an electrode is (8, 9) for a Spark Plug, the made of a base material (11) and at least one in the base material. (11) dispersively distributed Filler (12) formed is is embedded in the base material and a metal oxide is and by a negative enthalpy of greater than 800 kJ/mol O 2 is characterized, described. The base material (11) is-or Rh-base material or an Au pure Au or Rh, wherein the proportion of the filler material (12) between 5 vol- % and 50 vol- %. Alternatively, are as base material (11) Pt- basis materials or pure Pt provided, wherein the proportion of the filler material (12) at average particle diameters of (D50) of the filler material (12) between 5 µm and 20 µm between 50 vol % and 21% by volume or the additional material (12) at least one metal oxide selected from the group of the rare earth metal oxides and/or at least one metal oxide selected from the group 2 O3 Al, Y 3 2 O, Sc 3 2 O, CaO, SrO, BaO and/or at least one mixed oxide, such as spinel, from at least an alkaline earth metal oxide, a rare earth metal oxide, 3 2 O Al, Y 3 2 2 O3 O is and/or Sc, wherein the proportion of the additive (12) 5 vol- % and 50 vol- % between.
