Abstract: Disclosed are a dedusting apparatus, a battery manufacturing device, and a dedusting method. The dedusting apparatus is used for removing dust on the surface of a material belt, and includes a dust suction mechanism and a magnetic mechanism, wherein the magnetic mechanism is arranged opposite to the dust suction mechanism at an interval to form a gap for the material belt to pass through, and the magnetic mechanism is used for generating an alternating magnetic field. By arranging the magnetic mechanism and the dust suction mechanism opposite to each other on both sides of the material belt in the thickness direction, when the material belt passes through the gap between the magnetic mechanism and the dust suction mechanism, metal dust passing through the gap along with the material belt is affected by the alternating magnetic field and induced to form an eddy current.
