Abstract
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.
