Laminated coil component and method for manufacturing same
A laminated coil component that has DC superimposition characteristics improved without causing an increase in direct-current resistance, and reduces stress which can be generated in a magnetic body. A laminated coil component includes a magnetic section of magnetic layers stacked and a conductor section which has a plurality of conductor pattern layers arranged between the magnetic layers, and interconnected in a coiled shape to pass through the magnetic layers, and which is buried in the magnetic section. The conductor section is composed of a conductor containing silver. The magnetic section is of a sintered ferrite material containing Fe2O3, NiO, ZnO, and CuO. The ratio of the Cu content (in terms of CuO) in a near-conductor section region of the magnetic section to the Cu content (in terms of CuO) in a central region of the magnetic section is 0.2 to 0.5.
