Abstract: In a multilayer filter, first and second resonant circuits are arranged in a direction crossing a stacking direction of a plurality of dielectric layers. An input/output portion includes an input/output port group including an unbalanced port and a pair of balanced ports or an input/output port group including two pairs of balanced ports. The second resonant circuit includes an inductor conductor, a first capacitor conductor, and a second capacitor conductor. The inductor conductor includes first and second ends. The first capacitor conductor is connected to the first end. The second capacitor conductor is connected to the second end. The second dielectric layer has a dielectric constant lower than that of the first dielectric layer. The first and second capacitor conductors are provided in the first dielectric layer. At least a part of the inductor conductor is provided in the second dielectric layer.

Abstract: An electronic component includes an element body having a pair of main surfaces facing each other, and a resonator disposed in the element body. The resonator has a first conductor and a second conductor disposed to face each other in a facing direction of the pair of main surfaces, and a coupling conductor extending in the facing direction and coupling the first conductor and the second conductor. A resonance space is formed by the first conductor, the second conductor, and the coupling conductor. The coupling conductor includes a plurality of coupling portions. At least a part of the plurality of coupling portions extends in one direction when viewed from the facing direction.

Abstract: An electronic component includes an element body formed by laminating a plurality of insulating layers, and a resonator disposed in the element body. The resonator includes a first conductor and a second conductor extending in a stacking direction of the plurality of insulating layers, and inductor conductors electrically connecting the first conductor and the second conductor. In at least one conductor of the first conductor and the second conductor, when the conductor is viewed from the stacking direction, a first length in one direction is longer than a second length in the other direction orthogonal to the one direction, and as viewed from the stacking direction, a direction in which the first conductor and the second conductor are arranged is orthogonal to the one direction.
