PROBLEM TO BE SOLVED: To provide a cartridge filter allowing easy attachment to a dust collector. SOLUTION: The cartridge filter has a filter body 1 which has a nearly cylindrical whole shape and a body wall having a bellows-like shape continuing in the circumferential direction, a nearly cylindrical connection section 2 which is arranged concentrically at one end of the filter body 1 and is to be attached to and removed from an attachment section of the dust collector, a cylindrical retainer 3 fixed concentrically to the connection section 2 and contained in the filter body 1, and two or more short cylindrical bands 4 which are attached and fixed annularly to the filter body 1 at appropriate intervals in the longitudinal direction of the filter body 1 so as to prevent excessive expansion of the filter body 1 and have elasticity.
