Document Type and Number:
WIPO Patent Application WO/2018/083936
Kind Code:
A1
Abstract:
Provided is a multilayer LC filter which has desired frequency characteristics, while being reduced in height. This multilayer LC filter is configured such that: when a laminate 1 is perspectively viewed from the lamination direction of dielectric layers, a first inductor L1 and a second inductor L2 are formed in a first flat surface region FD1, while a third inductor L3 and a fourth inductor L4 are formed in a second flat surface region FD2; and when the laminate 1 is perspectively viewed from a direction that is perpendicular to the lamination direction of the dielectric layers, the first inductor L1 and the fourth inductor L4 are formed in a first thickness region TD1, while the second inductor L2 and the third inductor L3 are formed in a second thickness region TD2.
