The purpose of the present invention is to obtain an igniter and a gas generator in which sealing properties and insulating properties are maintained, the elongation of a cup-shaped member during operation is adjusted, and ignition impediment on a starting mix is suppressed. A disc-type gas generator (100) is provided with a short substantially cylindrical housing in which one end and the other end in the axial direction are closed. A holding part (30) as internal components, an igniter (40) having a blast cap (43), a cup member (50), a starting mix (59), a gas generating agent (61), a lower support member (70), an upper support member (80), a buffer member (85), and a filter (90), etc. In order to make the elongation of the blast cap 43 greater than 0% and less than 10% when the igniter 40 is operated, the blast cap 43 is formed by molding a thermosetting resin or a thermoplastic resin containing an elongation adjusting material into a cup shape.
为得到一种能在保持密封性及绝缘性的同时,调节杯状部件工作时的伸长,抑制了对传火药的传火阻碍的点火器及气体发生器。盘型气体发生器100具有轴向一端及另一端被封闭的短尺寸大致圆筒状的壳体,在设置于该壳体内部的收容空间中,收容有作为内部构成部件的保持部30、具有爆破盖43的点火器40、杯状部件50、传火药59、气体发生剂61、下侧支撑部件70、上侧支撑部件80、缓冲部件85及过滤器90等。为了使点火器40工作时爆破盖43的伸长率为大于0%且小于10%,爆破盖43是将含有伸长率调节材料的热固性树脂或热塑性树脂成型为杯状而成的。
