The discharge lamp has a discharge vessel (10) and a socket (20) made of an electrically insulating material. Two electrodes (12, 13) project into the discharge vessel (10), with which electrical lines (16,17) are connected, which are conducted through the socket (20). A first electrically conductive component (22) is connected with the one line (16), and a second electrically conductive component (26) is connected with the other line (17), surrounds the first component (22) and is separated from it by the insulating material of the socket (20). The two components (22, 26), together with the insulating material of the socket (20), constitute a capacitive component, which is switched in parallel between the two lines (16,17), thus preventing or at least reducing the spreading of electromagnetic interference along the lines (16,17).
