Initiator and gas generator

摘要

In order to provide an initiator that can be easily produced at a low production cost and that can reduce the size of a connector, and a gas generator using the initiator, a reactant (58) is contained in a casing (56) of an initiator (50). An electrode pin (62) is fitted in a hole (66) of a header (54) and is fixed by glass or the like. A bridge wire (68) is provided between the electrode pin (62) and the header (54). A cylindrical terminal (54A) protrudes from the header (54), and the electrode pin (62) extends through the cylindrical terminal (54A). A connector-retaining portion (54a) is provided at the leading end of the cylindrical terminal (54A).
