<p>Provided is a noise filter array wherein characteristic variance among a plurality of filter elements is eliminated while maintaining a simple configuration as a whole. The filter elements (F1-F4) composed of an LC parallel resonance circuit and the LC serial resonance circuit, which have coils and capacitors, are arranged in parallel in an array and integrally formed. Grounding capacitors (C12-C42) which configure the filter elements (F1-F4) are arranged by having their grounding side electrode (9) commonly face each signal side electrode (8). The grounding capacitors are connected to an inductance adjusting conductor (L0), which configures the LC serial resonance circuit with the capacitor through a via hole (7). The lengths from the connecting position of the via hole (7) of the inductance adjusting conductor (L0) to grounding terminals (GND1, GND2) are made equivalent for each of the filter elements (F1-F4).</p>
