Zusammenfassung:An igniter element has two contacts (12, 13) which are on the contact side of a support body (11), and which are connected via a resistance element (15). By current feed to the contacts (12, 13), a primer mix (17) is ignited on one active side of the support body (11). The support body (11) is placed in a fixing device (10), whereby the former is fitted with at least one stop spring (18) which catches on a stop shoulder (21) of the holding device. Furthermore, the support body (11) has a recess (22) on the front-side in the region of the stop spring (18), which recess is open in the direction of the active side. After igniting the primer mix (17), pressure builds up on the active side, so that the outer surface (23) of the stop spring (18) is pressed against the inner surface of the fixing device (10).
