Title:
LAMINATED INDUCTOR AND POWER SUPPLY CIRCUIT MODULE
Document Type and Number:
WIPO Patent Application WO/2013/128702
Kind Code:
A1
Abstract:
Provided is a laminated inductor having excellent properties. A laminated inductor (100) is provided with a laminate body comprising laminated magnetic-body layers (101-108). The magnetic-body layers (102-107) have loop-shaped conductive wires (121-125) formed therein. The loop-shaped conductive wires (121-125) form a coil-conductive body having an axis in the laminate direction, by being connected via interlayer-connecting conductive bodies (141-144). One end of the conductive wire (121) at the topmost-layer-side end of the coil-conductive body is connected to a conductive wire (131), which is for routing and formed in a layer further toward the top, via an interlayer-connecting conductive body (151). The conductive wire (131) is also connected to an interlayer-connecting conductive body (152) formed so as to penetrate the substantial center on the inside of the loop-shaped conductive wires (121-125). The interlayer-connecting body (152) is connected to an externally-connecting conductive body (162) on the bottom surface of the laminate body, via the conductive wire (132) and an interlayer-connecting conductive body (153).
