Abstract
Multiple LC parallel resonators in which inductors and capacitors are connected in parallel are located inside a multilayer body. The inductors each include a loop inductor including a line-shaped conductor pattern and at least one pair of via conductors connected to the line-shaped conductor pattern. When the multilayer body is seen through in a height direction, in all the loop inductors of the LC parallel resonators, open via conductors are closer to a center of the multilayer body, and short-circuit via conductors are closer to an outer side of the multilayer body in at least one of a width direction and a length direction.
