The present invention relates to a squib used for a gas generator that operates an occupant protecting system of an automobile, such as a seatbelt pretensioner and an airbag system and to a producing method thereof. The invention provides a squib including a cup (2), an ignition agent (3) packed in the cup (2), a plug (4) to close an opening of the cup (2), two electrode pins (5, 6) inserted in the plug to extend through it, and a bridge wire (7) that is connected between the two electrode pins (5, 6) in the cup (2) and generates heat when electrically energized, wherein the two electrode pins (5, 6) are inserted in the plug (4) to extend through it in such a manner as to form projected portions (23) that are projected from one end of the plug on the cup side, wherein the bridge wire (7) is connected between the projected portions (23) of the electrode pins (5, 6), wherein the bridge wire (7) and the projected portions (23) are buried in the ignition agent (3), and wherein the bridge wire (7) and the ignition agent (3) are sealed in the cup (2) in the condition in which they have a certain contact pressure acting on each other. Also, the present invention provides a producing method thereof. <IMAGE> |
