Title: LAMINATED LC FILTER
Abstract:
Provided is a laminated LC filter that has small insertion loss and that is equipped with an inductor having a large inductance value and a high Q value. The present invention is provided with: a laminate body 1 in which dielectric layers 1a-1s are laminated; second track-like conductor patterns 8a-8d; third track-like conductor patterns 9a-9d; first track-like conductor patterns 10a-10d; capacitor conductor patterns 5a-5f; ground conductor patterns 6a, 6b; and via conductors 4a-4o, wherein, in a perspective view of the laminate body 1 in the laminating direction of the dielectric layers, the first track-like conductor patterns 10a, 10c and the third track-like conductor patterns 9a, 9c intersect with each other in a first inductor L1, and the first track-like conductor patterns 10b, 10d and the third track-like conductor patterns 9b, 9d intersect with each other in a second inductor L2.
