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.

[ What is claimed is:] [4.]4. A process of producing a propellant charge igniter for cartridge ammunition of the type including an ignition tube containing a booster charge, wherein the ignition tube is composed of a sheathing tube closed at one end and provided with radially extending ignition openings, and a thin-walled protective tube that is closed at one end and is arranged inside the sheathing tube to protect the booster charge, with the protective tube resting with its closed end against the closed end of the sheathing tube, and with its external circumferential wall against the internal circumferential wall of the sheathing tube and covering the ignition openings; said method including: inserting the protective tube into the sheathing tube; and subsequently injecting a sealing agent into the ignition openings of the sheathing tube to fill the ignition openings with the sealing agent and such that the sealing agent can penetrate from the ignition openings into a space between the protective tube and the sheathing tube.
