Abstract: In a filter, LC parallel resonators are arranged along an x-axis direction of a multilayer body and include coils and capacitors, respectively. LC parallel resonators adjacent to each other in the x-axis direction are electromagnetically coupled to each other. Each of the coils includes line conductor layers disposed on an insulating layer, a first via-hole conductor that extends from the line conductor layers to a negative direction of a z-axis direction and that is electrically connected to one conductor layer of the corresponding one of the capacitors, and a second via-hole conductor that extends from the line conductor layers to the negative side of the z-axis direction and that is electrically connected to the other conductor layer of the capacitor. A coupling conductor layer provides a capacitance between two line conductor layers which are adjacent to each other in the x-axis direction.

Abstract: An electronic component includes a multilayer body including dielectric layers, a circuit pattern, and band-shaped conductor patterns. The circuit pattern includes a conductor pattern that is disposed inside the multilayer body and defines an inductor. The band-shaped conductor patterns are grounded and cover a portion of a shield surface. An internal surface is located between the circuit pattern and an upper surface. On a shield surface, a non-shielded area is provided which is not covered with any of the band-shaped conductor patterns, and through which magnetic flux generated from the inductor is able to pass.

Abstract: A capacitor of a certain LC resonator, among multiple LC resonators in a band-pass filter, is arranged at a side of one main surface in a stacking direction of a multilayer body of the band-pass filter and the capacitors of the remaining LC resonators are arranged at a side of the other main surface in the stacking direction of the multilayer body. One of a pair of capacitor electrodes of the capacitor of the certain LC resonator is grounded. The one capacitor electrode that is grounded covers at least the plurality of LC resonators, as viewed from the stacking direction of the multilayer body.
