PROBLEM TO BE SOLVED: To provide a dust collector which strengthens momentum of air blown off from a nozzle to elongate the arrival distance, thereby enhancing the removal efficiency of dust and which is capable of uniformly and surely cleaning the whole surface of a material to be cleaned by jetting stable, strong and uniform air over the whole length of the nozzle longitudinal direction. SOLUTION: In the dust collector 2 which is provided with an air supply chamber 20 to which hyperbaric air is supplied, a carriage conduit 60 to which the material P to be cleaned is conveyed, a slit nozzle 16 communicating with the air supply chamber 20 arranged as a longitudinal direction which is almost the right-angled direction to the carriage direction of the carriage conduit 60 and an air conduit 15 communicating between the air supply chamber 20 and the nozzle 16, the air conduit 15 is shrunk in plural stages between the opening part 14 of the air supply chamber 20 side and the air conduit 15 end part in the section right-angled to the longitudinal direction.
