To provide a gas generator that facilitates installing a filter to a housing compared to conventional ones.SOLUTION: A lower side shell 10 of a gas generator 100 has a bottom plate part 11 and a peripheral wall part 12, and an upper side shell 20 has a top plate part 21 and a peripheral wall part 22. The peripheral wall part 12 has a cylindrical first peripheral wall part 12a extending toward the upper side shell 20 side from a peripheral edge part of the bottom plate part 11, and a cylindrical second peripheral wall part 12b extending in a staircase manner toward the upper side shell 20 side from an end part of the first peripheral wall part 12a and having a diameter larger than that of the first peripheral wall part 12a. A filter material 70 is such that an outer diameter of one end part and the other end part thereof in an axial direction is formed smaller than an outer diameter of a part except the one end part and the other end part before installation to the lower side shell 10, and an outer diameter of a part except the one end part and the other end part in the axial direction is formed larger than an inner diameter of the first peripheral wall part 12a and the same diameter as an inner diameter of the second peripheral wall part 12b or smaller than the inner diameter of the second peripheral wall part 12b.SELECTED DRAWING: Figure 1
