3. An LC resonator comprising:
a first plane electrode;
a second plane electrode opposed to at least a portion of the first plane electrode in a specific direction;
a first line electrode;
a first via conductor and a second via conductor extending from the first line electrode in the specific direction to be connected to the first plane electrode and the second plane electrode, respectively; and
a third plane electrode opposed to at least a portion of the second plane electrode in the specific direction; wherein
the second plane electrode is between the first plane electrode and the third plane electrode in the specific direction;
the third plane electrode is a ground electrode;
the second plane electrode and the ground electrode define a capacitor; and
the first plane electrode and the second plane electrode define another capacitor.
