Abstract: A gas generator includes a housing main body made of metal, a holder assembly, and an igniter. The holder assembly includes a holder portion made of metal and a connector portion made of resin. The holder portion includes a first barrel portion and an annular projection. The connector portion includes a second barrel portion and a cylindrical portion. The cylindrical portion is inserted in the housing main body and externally attached to the first barrel portion. As a portion of the housing main body corresponding to the cylindrical portion is decreased in diameter, the cylindrical portion is compressed by being sandwiched between the portion of the housing main body decreased in diameter and the first barrel portion so as to seal a gap between the housing main body and the first barrel portion.
