1. A resonant device comprising:
a multilayer body;
a first plane electrode provided to the multilayer body;
a second plane electrode provided to the multilayer body;
a third plane electrode provided to the multilayer body and located between the first plane electrode and the second plane electrode in a normal direction of the first plane electrode;
a first via electrode and a second via electrode connecting the first plane electrode and the third plane electrode; and
a third via electrode and a fourth via electrode connecting the first plane electrode and the second plane electrode; wherein
when the first plane electrode is seen in a plan view in the normal direction, a first imaginary line connecting the first via electrode and the second via electrode intersects with a second imaginary line connecting the third via electrode and the fourth via electrode; and
the second plane electrode and the third plane electrode define a capacitor.
