Abstract: A process of producing a propellant charge igniter for cartridge ammunition of the type including an ignition tube with a booster charge, wherein the ignition tube is composed of a sheathing tube (4) with ignition openings (3) and a thin-walled protective tube (6) which is arranged inside the sheathing tube (4) in order to protect the booster charge, and wherein the external wall of the protective tube fits against the internal wall of the sheathing tube (4) and covers the ignition openings (3). To avoid microscopic gaps between the sheathing tube and the protective tube, which gaps influence the performance of the propellant charge igniter, a paste-like sealing agent (5) is introduced into the sheathing tube (4) before the protective tube (6) is inserted into the sheathing tube (4), and only then is the protective tube (6) inserted into the sheathing tube (4) to displace the sealing agent. Alternatively with the protective tube (6) being fully inserted, the ignition openings (3) in the sheathing tube (4) are filled with a sealing agent (5) and then the protective tube (6) as well as the sheathing tube (4) are moved axially, relative to each other.
