Claim 1:
2. A layered low-pass filter comprising:
a first inductor and a second inductor connected in series;
a third inductor provided between a connection point of the first inductor with the second inductor and a ground;
a capacitor connected to the third inductor; and
a stack including a plurality of dielectric layers and a plurality of conductor layers stacked together, the stack being intended to integrate the first inductor, the second inductor, the third inductor, and the capacitor, wherein
the third inductor includes a first inductor portion and a second inductor portion connected in parallel,
the plurality of conductor layers include a first inductor-forming conductor layer, a second inductor-forming conductor layer, and a capacitor-forming conductor layer,
the first inductor-forming conductor layer constitutes at least a part of each of the first and second inductors,
the second inductor-forming conductor layer constitutes the first and second inductor portions,
the capacitor-forming conductor layer constitutes a part of the capacitor, and
the stack further includes a first through hole connecting the first inductor-forming conductor layer and the second inductor-forming conductor layer.
