Title:
LAMINATED COIL COMPONENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/024807
Kind Code:
A1
Abstract:
Provided is a laminated coil component in which DC superimposition characteristics are improved, and stress that may occur in the magnetic body is reduced, without resulting in an increase in DC resistance. A laminated coil component (11) having: a magnetic section (2) obtained by layering magnetic layers; and a conducting section (3) obtained by installing a plurality of conducting pattern layers between the magnetic layers so as to penetrate the magnetic layers, the conducting pattern layers being connected to each other in a coil configuration and embedded in the magnetic section (2); the conducting section (3) comprising a conductor containing silver; the magnetic section (2) comprising a sintered ferrite material including Fe2O3, NiO, ZnO, and CuO; and the Cu content (in terms of CuO) in the magnetic section (2) in the vicinity of the conducting section, relative to the Cu content (in terms of CuO) in the center region of the magnetic section (2), being 0.2-0.5.
