Abstract: A notch filter 100 includes a varistor 1 that is connected between a signal line SL and a ground G. The varistor 1 has a capacitive component and outputs a signal with a second frequency different from a signal with a first frequency flowing in the signal line SL and a signal with the second frequency superimposed on the signal line SL to the ground G.
