PURPOSE: A magnetic substance inserted injection molding for a noise suppressor is provided to attenuate noise generated from a conductor by using an internal magnetic substance and an external magnetic substance and obtain a finished product including a label by performing an injecting process once. CONSTITUTION: A plurality of metallic conductor(2,2-1) is formed in the inside of a magnetic injection substance(1). The inside and the outside of the metallic conductors(2,2-1) are coated by a magnetic composite(3). An outer side of the magnetic injection substance(1) is coated by an insulating material(4). The magnetic composite(3) is formed by mixing one of 50 to 95 weight percent selected from Mn-Zn, Ni-Zn, Mn-Mg-Zn, Mg-Cu-Zn, Ni-Cu-Zn ferrite powders, Fe powders, and permalloy powders and one of 5 to 50 weight percent selected from a thermosetting resin, a thermoplastic resin, and a rubber material.
