A noise filter array includes filter elements including an LC parallel resonant circuit and an LC series resonant circuit each of which includes a coil and a capacitor provided in proximity in an array and integrally provided with one another. The LC series resonant circuits include ground capacitors having signal-side electrodes. Inductance adjustment conductors are connected to signal-side electrodes of the capacitors defining the respective filter elements, and a ground electrode of the capacitors is commonly arranged so as to oppose the signal-side electrodes.

A noise filter array includes filter elements, each of which includes an LC parallel resonant circuit having a coil and a capacitor and an LC series resonant circuit having a coil and a capacitor, are arranged substantially parallel to one another in an array and integrally provided. Grounding capacitors that define the filter elements are arranged so that a common ground-side electrode faces signal-side electrodes and is connected to an inductance adjusting conductor that defines the LC series resonant circuits along with the capacitors through a via hole. The lengths of the inductance adjusting conductor from a connection location within the via hole to ground terminals are substantially equal in each of the filter elements.

A noise filter includes a plurality of LC parallel resonant circuits having a plurality of coils which are connected in series and electrically connected to external electrodes at both ends thereof, and capacitors which are connected in parallel to the coils, respectively, and are disposed inside an insulator while being sequentially connected in tandem to signal wires. Resonance frequencies of the respective LC parallel resonant circuits are preferably different from each other. Further, a shield electrode is disposed between the coils, and the shield electrode also defines a capacitance-forming electrode for preventing magnetic coupling between the two coils.
