发明名称 LAMINATED COIL COMPONENT
摘要 Provided is a laminated coil component that exhibits excellent DC superimposition characteristics and can use copper, which is inexpensive, as an internal conductor. Said laminated coil component has the following: a magnetic body comprising a ferrite material; a non-magnetic body comprising a non-magnetic ferrite material; and a conductive part consisting primarily of a coil of copper embedded inside the magnetic body and the non-magnetic body. The non-magnetic body contains at least iron, manganese, and zinc, and may optionally contain copper. In terms of Fe2O3, the iron content of the non-magnetic body is between 40.0 mol% and 48.5 mol%, inclusive; in terms of Mn2O3, the manganese content of the non-magnetic body is between 0.5 mol% and 9 mol%, inclusive; and in terms of CuO, the copper content of the non-magnetic body is at most 8 mol%.
