A gas generator including a plug (24) having a header part (45) and two or
more electrode pins (22, 23), a thin-film bridge (25) having electrode
pads (41, 42), and a squib (10) in which upon supply of electric current
to the thin-film bridge (25) via the electrode pins (22, 23), the
thin-film bridge (25) is activated to ignite ignition materials (26, 27),
wherein the thin-film bridge (25) is arranged into a hollow (32) prepared
at the plug (24) in such a manner that the thin-film bridge (25) is kept
approximately on a level with the head (35) of the electrode pins (22,
23) and the header part (45) of the plug (24), the thin-film bridge (25)
is connected by wire bonding to the electrode pins (22, 23) at the
electrode pad parts (41, 42), and at least either of the electrode pad
(41) or (42) of the thin-film bridge (25) is connected by the wire
bonding to a metal part of the header part (45) of the plug (24).
