Abstract: In an electronic component, first through n-th LC parallel resonators respectively include first through n-th inductors disposed in a device body such that they are sequentially arranged in a first direction in an order from the first inductor to the n-th inductor. The first and the n-th inductors are wound around respective winding axes extending along the first direction. At least one predetermined inductor among the second through the (n−1)-th inductors is wound around a winding axis extending in a second direction which is perpendicular or substantially perpendicular to the first direction. A center of the predetermined inductor in the second direction is positioned toward one side of the second direction with respect to the winding axes of the first and the n-th inductors, as viewed from a plane of the device body in a third direction which is perpendicular or substantially perpendicular to the first and second directions.

Abstract: A multilayer bandpass filter includes a first capacitor electrode of a first stage LC parallel resonator, a second capacitor electrode of a second stage LC parallel resonator, and a third capacitor electrode of a third stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the first stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the second stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the third stage LC parallel resonator. The inductor electrodes of the three LC parallel resonators are arranged so loop planes thereof are disposed about a center axis extending in a stacking direction of dielectric layers. This permits setting of electromagnetic coupling between the LC parallel resonators of an input and an output stage, and allows a filter's attenuation characteristics to be freely set.
