An electric lamp has a lamp vessel (1) and is provided with an illumination source (2). A central current-supply conductor (3) and a side current-supply conductor (4) issue from the lamp vessel. The electric lamp has a lamp base (5) for providing a mechanical connection of the lamp vessel and for providing a mechanical and electrical connection of the current-supply conductors. At a side facing the lamp vessel, the lamp base is provided with a notch (6) for passing through the side current-supply conductor. At a side facing away from the lamp base, the side current-supply conductor is provided with a coagulated droplet of material of the side current-supply conductor. Preferably, the coagulated droplet is made by laser heating of a portion of the side current-supply conductor issuing from the notch. According to the invention, the side current-supply conductor is reliably connected to the lamp base while soldering is dispensed with.
