Title:
METHOD FOR MANUFACTURING LAMINATED COIL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2014/013896
Kind Code:
A1
Abstract:
This manufacturing method includes: a laminate block fabrication process wherein a laminate block, that is, a collective body of multiple laminates, is fabricated by alternately layering a magnetic body layer, which has a magnetic metal material as a major component and contains a glass material, and a conductor layer containing a conductive material such that the conductor layers are electrically connected together so as to form a coil pattern; a dividing process wherein the laminate block is cut and divided into respective laminates; a magnetic material application process wherein a magnetic material containing the magnetic metal material is applied to side surface sections of the laminate; and a firing process wherein a base component (1) is fabricated by firing the laminate to which the magnetic material was applied. The base component (1) is formed from a main magnetic body (8) which contains the magnetic metal material as a major component and the glass material as a minor component; and magnetic material-applied sections (9a, 9b) which comprise the magnetic material and are formed on the side surface sections of the main magnetic body (8). Consequently, a method for manufacturing a laminated coil component which has improved reliability and is suitable as a power inductor can be achieved without impairing direct-current superimposition characteristics.
