An electro-pyrotechnic initiator includes two electrical pins (7) for supplying current, a pyrotechnic composition (4) stored in a receptacle (2, 3) and a bridge (23) establishing an electrical connection between the two pins (7). The bridge (23) is set down on a wafer (11), the bridge (23) and the wafer (11) forming part of an electronic micro-component (20) to which the pins (7) are connected. The composition (4) is compacted in the receptacle (2, 3), the composition (4) and the micro-component (20) being brought together under pressure in the receptacle (2, 3). A housing for a helium saturated material is provided at a bottom of the receptacle.
