In a noise filter, an input side of a signal-line lead is inserted in a first substantially cylindrical ferrite bead, and an output side of the signal-line lead is inserted in a second substantially cylindrical ferrite bead. An input side of a ground lead is inserted in a third substantially cylindrical ferrite bead. The signal-line lead is inserted in a feedthrough capacitor such that the feedthrough capacitor is adjacent to an output side of the second substantially cylindrical ferrite bead. A multilayer capacitor is electrically coupled between the signal-line lead and the ground lead such that the multilayer capacitor is adjacent to an output side of the first substantially cylindrical ferrite bead and adjacent to an output side of the third substantially cylindrical ferrite bead. Each of an end of the signal-line lead and an end of the ground lead is flat, bent along an outer surface of a base member, and defines a surface-mount external terminal.
