Abstract
A low pass filter includes a first input/output terminal, a second input/output terminal, a signal line, inductors connected in the signal line, and capacitors connected between the signal line and ground. In the signal line, a capacitor is connected in parallel to the inductor that is connected closest to the first input/output terminal, and the inductor and the capacitor define a first parallel resonator.
