PROBLEM TO BE SOLVED: To provide a dust removing device that can secure a sufficient amount of absorption even if the separation is reduced between a suction nozzle and a body to be treated, and can remove dust efficiently by inducing a vortex flow in the fresh air to be sucked. SOLUTION: The dust-removing apparatus A comprises the cylindrical suction nozzle 1; a sucking means for sucking the fresh air from the side of a tip 1b of the suction nozzle 1, while being connected to the rear end of the suction nozzle 1; and a holding stand that arranges the body 3 to be treated, so that it opposes the tip 1b of the suction nozzle 1 and holds the body 3 to be treated, thus removing dust adhering to the body 3 to be treated by sucking the fresh air by the suction nozzle 1 while the tip 1b is brought closer to the body 3 to be treated. In the dust-removing device A, a groove 5 connected from an outer surface 1c to an inner surface 1d in the suction nozzle 1 is provided at the tip 1b of the suction nozzle 1, and the groove 5 is formed so that a center line O1 of the groove 5 crosses the direction of the diameter of the tip 1b of the suction nozzle 1.
