Abstract: An electronic component includes a multilayer body including insulating layers that are stacked on each other. First and second LC parallel resonators each include via hole conductors extending in a z-axis direction and loop shaped conductive layers provided on the insulating layers. The first and second LC parallel resonators define a band pass filter. A first loop plane of the first LC parallel resonator and a second loop plane of the second LC parallel resonator are parallel or substantially parallel to the z-axis direction, are parallel or substantially parallel to each other, and are overlapped with each other at at least a portion of the first loop plane and the second loop plane in a plan view from the direction perpendicular or substantially perpendicular to the first loop plane. The first loop plane protrudes from the second loop plane at the positive direction in the z-axis direction.

Abstract: In a high frequency filter, a multilayer structure includes a plurality of insulator layers, a first transmission line transmits an input signal, and a second transmission line is electromagnetic coupled with the first transmission line on the same insulator layer and transmits an output signal. A conductor layer defines capacitors with the first transmission line and the second transmission line with the insulator layer in between. A dielectric constant of the insulator layer that comes in contact with the first transmission line and the second transmission line is higher than a dielectric constant of an insulator layer other than the insulator layer.

Abstract: In a directional coupler, sub-lines or main lines are electromagnetically coupled to each other to degrade isolation characteristics. A capacitor is located between the sub-lines or between the main lines to cause the isolation characteristics to have poles in order to improve the isolation characteristics of the directional coupler.

Abstract: An LC resonator includes an external connection terminal, an inductor, a capacitor, and a via conductor pattern. The inductor winds around an axis orthogonal to a laminated direction. The capacitor is connected to the inductor. The via conductor pattern extends from the inductor in the laminated direction, and the inductor is connected to the external connection terminal with the via conductor pattern. The inductor includes a columnar conductor pattern extending in the X-axis direction. The area of the columnar conductor pattern in a plan view from the X-axis direction is greater than or equal to the area of the via conductor pattern in a plan view from the Z-axis direction.
