積層インダクタ部品およびその製造方法
Document Type and Number:
Japanese Patent JP7059520
Kind Code:
B2
Abstract:
To provide a lamination inductor component in which coil wiring above and below a nonmagnetic layer can be prevented from conducting via a crack in the nonmagnetic layer.SOLUTION: A lamination inductor component has an elementary body constituted by laminating a magnetic layer and a nonmagnetic layer in the lamination direction, and a coil provided in the elementary body, and wound spirally. The coil is constituted by laminating multiple coil wiring wound planarly in the lamination direction, the nonmagnetic layer is placed between upper and lower coil wiring adjacent in the lamination direction, and extends to the width direction outside of the upper and lower coil wiring, the nonmagnetic layer and the lower coil wiring come into contact with each other, while the magnetic layer is interposed between both ends of the lower coil wiring in the width direction and the nonmagnetic layer, and the nonmagnetic layer and the upper coil wiring are in contact with each other, while the magnetic layer is not interposed between both ends of the upper coil wiring in the width direction and the nonmagnetic layer.SELECTED DRAWING: Figure 2
