Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for deburring a dust core without causing damages to the dust core. SOLUTION: In the production process of a dust core comprising a step for molding material powder produced by mixing soft magnetic metal powder and resin powder into a desired shape by die molding, and a step for heat treating a molding thus obtained and bonding the metal power by the resin powder, a step for deburring the molding at the molding step is provided prior to the heat treatment step, and a method for spraying a media having a particle size of 10-200 μm to the molding, together with gas, is applied as the deburring step.
