Described is an igniter comprising an arrangement composed of an ignition electrode, an outer conductor coaxially enclosing the ignition electrode, and an electric insulator disposed between the ignition electrode and the outer conductor, via which insulator the ignition electrode and the outer conductor are interconnected, for igniting a fuel/air mixture in a combustion chamber, in particular in an internal combustion engine comprising one or more combustion chambers which are delimited by walls that are at ground potential, by creating a corona discharge in an area surrounding the tip of the ignition electrode. According to the invention, the ratio of the outer diameter d of the ignition electrode and the inner diameter D of the outer conductor is in the range of 0.3 to 0.44.
