Abstract
In a high-pressure discharge lamp including a ceramic discharge vessel, a secure connection between a hybrid antenna as starting aid and a leadthrough of the discharge vessel is provided by virtue of the fact that a means between leadthrough and extension limits the ohmic resistance between leadthrough and hybrid antenna preferably to at most 100Ω.
