A lamp base ( 2 ) for a high-pressure discharge lamp comprises an ignition transformer ( 1000 ), which is placed in the interior ( 214 ) of the lamp base ( 2 ) and which serves to ignite the gas discharge inside the high-pressure discharge lamp. To this end, the ignition transformer ( 1000 ) comprises a core on which its windings ( 1001, 1002 ) are placed. The core is formed by a first core part ( 1004 ) and by at least one second core part ( 1005, 1006, 1007 ), which are each made of a ferromagnetic or ferrimagnetic material and are separated by at least one gap ( 10078 ). The first core part ( 1004 ) has a cylindrical section on which the windings ( 1001, 1002 ) of the ignition transformer ( 1000 ) are placed, and core parts ( 1004, 1005, 1006, 1007 ) are formed in such a manner that the core, apart from the at least one gap ( 1008 ), has a closed shape.
