A cylindrical filter for a gas generator includes, a plurality of layers made of a porous metal plate in which a compressive strength (S1) of a predetermined region in at least one end in the height direction is set smaller than a compressive strength (S2) of a portion other than the S1 region, the porous metal plate being selected from the group consisting of expanded metal, metal lath, and perforated metal, and the S1 region corresponding to a region of 5 to 20% in length from both ends with respect to the overall height. |
