Abstract:
In a laminated LC filter, at least four LC parallel resonators are provided inside a multilayer body. At least a pair of loops of inductors in odd numbered-stage LC parallel resonators among the at least four LC parallel resonators are disposed at an angle at which magnetic coupling is obtained therebetween, and winding directions thereof are the same, so as to obtain magnetic coupling between the inductors. In addition, magnetic coupling may also be obtained between a pair of loops of inductors in even numbered-staged LC parallel resonators among the at least four LC parallel resonators.
