ABSTRACT:
A layered low-pass filter includes: a first coil and a second coil that are connected in series and that are located between an input terminal and an output terminal in terms of circuit configuration; and a capacitor located between a ground and a node between the first and second coils in terms of circuit configuration. In terms circuit configuration, the first coil is located closer to the input terminal than is the second coil. Each of the first and second coils has an input and an output. The layered low-pass filter further includes: a first conducting path formed using at least one through hole and used for connecting the capacitor to the output of the first coil; and a second conducting path formed using at least one through hole and used for connecting the capacitor to the input of the second coil.
