The injection valve includes a valve housing of ferromagnetic material, in which a tubular connection element which functions as a core with which an armature is arranged to cooperate. Joined to the valve housing is a nozzle body having a valve seat with which a sealing section of a nozzle needle also arranged to cooperate.
