摘要： A diplexer includes a low-band band pass filter between a common input/output terminal and a low-band input/output terminal and a high-band band pass filter between the common input/output terminal and a high-band input/output terminal, wherein the low-band band pass filter includes LC resonators including a first-stage LC resonator to a final-stage LC resonator in order from the common input/output terminal toward the low-band input/output terminal, the high-band band pass filter includes LC resonators including a first-stage LC resonator to a final-stage LC resonator in order from the common input/output terminal toward the high-band input/output terminal, a matching capacitor is between the common input/output terminal and the low-band band pass filter, and the capacitance of a capacitor of the first-stage LC resonator of the low-band band pass filter is smaller than the capacitance of a capacitor of the final-stage LC resonator.

摘要： A diplexer includes a first filter circuit including a first loop inductor defining a first loop plane and a second loop inductor defining a second loop plane, a second filter circuit adjacent to the first filter circuit, and a first via hole conductor that electrically connects an input/output terminal, the first filter circuit and the second filter circuit to each other. The first loop plane faces the second loop plane while protruding beyond the second loop plane in a first direction. The first via hole conductor is provided relative to the first loop inductor in a second direction from the first loop plane toward the second loop plane, and is superposed with a portion of the first loop plane that protrudes beyond the second loop plane when viewed in the second direction.

摘要： An electronic component includes: a body having a first surface; and a plurality of electrodes disposed on the first surface. Each of the plurality of electrodes includes a base electrode and a plating film covering the base electrode. The plurality of electrodes include: first-class electrodes individually disposed on the first surface and connected to each other by a wiring line passing through an inside of the body; and a second-class electrode individually disposed on the first surface and not connected to other electrodes of the plurality of electrodes. On the first surface, a second region in which the second-class electrode is disposed more protrudes than a first region in which each of the first-class electrodes is disposed.
