Document Type and Number:
WIPO Patent Application WO/2011/058945
Kind Code:
A1
Abstract:
Disclosed is a laminated ceramic electronic component capable of reducing noise occurring in via electrodes in a base layer. Specifically disclosed is a laminated ceramic electronic component which comprises a base layer (2), a coil pattern (9) that is disposed inside the base layer (2) and that generates a magnetic field inside the base layer (2), and via electrodes (8) that are at least partially disposed inside the base layer (2). Peripheral portions of the via electrodes (8) that are in contact with the base layer (2) are covered with low-magnetic layers (14) of which permeability is lower than that of the base layer (2).
