Title:
MANUFACTURING METHOD FOR STACKED INDUCTOR ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/002116
Kind Code:
A1
Abstract:
On a main surface of magnetic or non-magnetic ceramic layers (SH1 to SH4) constituting a portion of a laminate (12), conductor patterns (CP1 to CP4) extending in loops are formed. Furthermore, via hole conductors, which extend in a Z-axis direction so as to form inductors together with the conductor patterns (CP1 to CP4), are formed on the laminate (12). Each of the conductor patterns (CP1 to CP4) has a conductor pattern of a first-layer embedded in the interior of the layer, and a conductor pattern of a second-layer exposed on the top of the layer. Furthermore, the ceramic layers (SH1 to SH4) are formed of materials comprising a ceramic paste which is applied, after the conductor pattern of the first-layer is formed on a ceramic sheet, to the main surface of the ceramic sheet so as to avoid the center in the width direction of the conductor pattern of the first-layer.
