Abstract
An electrode for a spark plug includes an electrode base material and a noble metal element, the noble metal element being fastened to the electrode base material using a welding connection. The welding connection has a maximum extension perpendicular to an area of the electrode at which the noble metal element is fastened, and the welding connection has a maximum width at the area. A ratio of the maximum extension to the maximum width is greater than, or equal to 3.
