A propellant charge igniter for cartridge ammunition, includes an ignition tube; and a transfer charge disposed within the ignition tube, wherein the ignition tube is composed of a jacket tube having defined therein a plurality of ignition openings; and a protective tube which is positioned within the jacket tube so that the outside wall of the protective tube rests flush against the inside wall of the jacket tube and covers the plurality of ignition openings, which is thin-walled and has a wall thickness ranging from 0.1 mm to 0.8 mm, which is arranged to effectively protect the transfer charge against adverse external environmental influences including humidity, and which is comprised of a material selected from the group consisting of glass, oxide ceramic material, glass ceramic material, metal or metal alloy, and plastic. This arrangement provides a reliable sealing of the transfer charge against external environmental influences over a long time period, e.g., at least 10 years, even if handled roughly.
