PROBLEM TO BE SOLVED: To provide a dust-analyzing system for obtaining the measurement result of dust in real time with less exchange frequency of filter materials. SOLUTION: The dust-analyzing system comprises a filter material 2 that is arranged while facing the passage of a gas containing dust and allows the dust to adhere, a feeder 7 for feeding the filter material 2 to an adhesion position intermittently in the longitudinal direction and for allowing an adhesion region (a) consisting of one portion of the filter material 2 to face the passage for specific time, and an X-ray analysis apparatus 6 that irradiates an adhesion region being sent to the downstream side in the feed direction than the adhesion position A with primary X rays and conducts the X-ray analysis of dust adhering to the adhesion region.
