A layered low-pass filter includes: a layered substrate; an input terminal, an output terminal and a grounding terminal each disposed on a periphery of the layered substrate; first and second inductors connected in series and provided between the input terminal and the output terminal; first to fifth capacitors formed within the layered substrate; a grounding conductor layer provided within the layered substrate; and a conducting portion formed within the layered substrate. The conducting portion includes a conductor layer connected to the grounding terminal, and a conducting path formed of a plurality of through holes. The conducting portion connects the grounding conductor layer to the grounding terminal via a path longer than the shortest distance between the grounding conductor layer and the grounding terminal.
