Title:
LAMINATED COIL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2007/037097
Kind Code:
A1
Abstract:
Provided is a laminated coil component allowing less inductance deterioration.
The laminated coil component is provided by laminating ceramic green sheets
(22a-22f) whereupon coil conductors (23a-23f) and via hole conductors (26a-26e)
are formed, and by incorporating a spiral coil (23) wherein the coil conductors
(23a-23f) are connected in series through the via hole conductors (26a- 26e).
In the plane view in the lamination direction, the via hole conductors (26b, 26d)
are positioned outside the spiral coil (23) on the end plane side in the long side
direction of a laminated body (30).
