The invention relates to an ignition device for the propulsive charge of a telescoped piece of ammunition, including a case (2) that is generally cylindrical in shape in which are housed a pyrotechnic composition (3) and a device (4) for ignition thereof. The case (2) has at least one end wall (6) traversed by several channels (10) which each extend along an axis (A1) that slopes in relation to the centre line (A) of the case (2). This device enables all the propulsive charge of a round of ammunition of the telescoped type to be ignited almost immediately.
