The invention relates to an electrode (12, 14) for a gas discharge lamp (10), the electrode (12, 14) having an electrode body (16) made of a first metallic material, and the electrode body (16) havinga hermetically sealed interior (18 ) includes. Furthermore, the electrode (12, 14) has a first heat-conducting component (20) made of a second metallic material, which is arranged in the interior (18), the second metallic material having a lower melting point than the first metallic material. In addition, a second non-metallic and non-gaseous thermal conductivity component (22) is arranged in theinterior (18), which has a higher thermal conductivity than gases (24). 本发明涉及一种用于气体放电灯(10)的电极(12，14)，其中电极(12，14)具有由第一金属材料构成的电极本体(16)，并且其中电极本体(16)包围气密地封闭的内部空间(18)。此外，电极(12，14)具有由第二金属材料构成的第一导热部件(20)，所述第一导热部件设置在内部空间(18)中，其中第二金属材料与第一金属材料相比具有较低熔点。此外，在内部空间(18)中设置有第二非金属的并且在标准条件下非气态的导热部件(22)，所述导热部件与气体(24)相比具有较高的热导率(λ)。
