23260-335 ABSTRACT OF THE DISCLOSURE An ignition device is disclosed which comprises a lower housing in which a sleeve is mounted containing the main charge of the ignition device. The ignition device utilizes an electric igniter device which includes an insulating body, an electric pole device and at least one electrically connecting element applied on one end surface of the insulating body for connecting the electric pole device and the electric ignition device housing. The elec- tric ignition device makes contact via the said end surface, against the layers and of pyrotechnical charges included in the ignition chain for the main charge. The said electric ignition device and layers of pyrotechnical charges are located inside a ring-shaped device from the first end of which the electric pole device protrudes. The ring-shaped device extends into the recesses and in the lower housing and the sealing part as well as across the space between these parts. The sealing part presses the pyrotechnical charges against the said end surface and the electrically connecting elements via the filler layer in the ring- shaped device. The electric ignition device is fixed in and sealed against the ring-shaped device which in turn is sealed against the lower housing by means of laser welding. The ignition device is useful in connection with artillery or anti-aircraft ammunition.
