The present invention provides a cylindrical filter for a pyrotechnic device including a gas generating agent or pressurized gas as a gas generation source. The cylindrical filter includes a first annular end surface, a second annular end surface positioned opposite to the first annular end surface in an axial direction, and a cylindrical wall surface between the first annular end surface and the second annular end surface. At least one of the first annular end surface or the second annular end surface includes a weakened portion. When the first annular end surface includes the weakened portion, the weakened portion includes a first annular wall portion that protrudes from the first annular end surface and has a thickness less than a thickness of the first annular end surface. When the second annular end surface includes the weakened portion, the weakened portion includes a second annular wall portion that protrudes from the second annular end surface and has a thickness less than a thickness of the second annular end surface.
