Abstract
An electrode () for a high-pressure discharge lamp, having an electrode head () and an electrode rod (), connected to electrode head () and defines a longitudinal axis (L). The electrode head () comprises a main section () on the same side as the electrode rod (), an intermediate section () and an end section () on the opposite side from the electrode rod (). The end surface of the end section () of the electrode head () is formed at least approximately semicircularly, and at least one subsection of the intermediate section () is cylindrically shaped. The extent (D) of the cylindrical subsection of the intermediate section () in at least one direction perpendicular to the longitudinal axis is greater than the diameter (D) of the semicircular end surface of the end section (), but less than the largest transverse extent (D) of the main section.
