PROBLEM TO BE SOLVED: To provide a cyclone dust collector capable of retaining high dust removal performance for a long time even when a gas contains particles of substances of low specific gravities. SOLUTION: A filter portion 3 capturing particles in a gas is arranged in the upper part of a cyclone portion 2 carrying out centrifugal separation of the particles in the gas, and a distributor 4 is arranged in the gas passage between the cyclone portion 2 and the filter portion 3. The particles contained in the gas are removed in three stages of centrifugal separation in the cyclone portion 2, falling under the resistance of the distributor 4 and filtration in the filter portion 3. Clogging of the filter portion 3 is thus controlled because relatively coarse particles are removed in the cyclone portion 2 and the distributor 4 in advance, and fine particles unremovable by the cyclone portion 2 and the distributor 4 can be captured by the filter portion 3.
