Abstract
A filter element includes series inductors connected in series to a signal path, shunt inductors shunt-connected between the signal path and ground, and a capacitor connected in series to the shunt inductors. The shunt inductors include first and second shunt inductors connected in parallel to each other. Conductive patterns of the capacitor are overlapped with coil opening portions of the series inductors and the shunt inductors viewed from a lamination direction. The capacitor is sandwiched between the first shunt inductor and the second shunt inductor in the lamination direction of insulating layers and the conductive patterns.
