An ignition device comprising a lower housing (1) in which a sleeve (2) is mounted containing the main charge (10) of the ignition device. The ignition device utilizes an electric igniter device (15) which includes an insulating body (19), an electric pole device (20) and at least one electrically connecting element applied on one end surface (19a) of the insulating body for connecting the electric pole device (20) and the electric ignition device housing (21). The electric ignition device makes contact via the said end surface (19a), against the layers (16) and (17) of pyrotechnical charges included in the ignition chain for the main charge (10). The said electric ignition device and layers of pyrotechnical charges are located inside a ring-shaped device (12) from the first end of which the electric pole device (20) protrudes. The ring-shaped device extends into the recesses (1a) and (9e) in the lower housing (1) and the sealing part as well as across the space (13) between these parts. The sealing part (9) presses the pyrotechnical charges against the said end surface (19a) and the electrically connecting elements via the filler layer (18) 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.
