PURPOSE: A distributed constant-TYPE noise filter for reducing radiant noise generated from a digital device is provided to minimize the size while maintaining a stable characteristic by maximizing inductor elements of a filter to reduce distribution capacity. CONSTITUTION: A noise filter includes a dielectric body, a signal input terminal electrode, a signal output terminal electrode, a ground terminal electrode, a signal coil, and a ground coil. The dielectric body(1) is formed by stacking a plurality of dielectric layers. The signal input terminal electrode(6), the signal output terminal electrode(7), and the ground terminal electrode(8) are formed on an outer surface of the dielectric body. The signal coil(2) is connected to the signal input terminal electrode and the signal output terminal electrode. A capacity element is formed between the signal coil and the ground coil. The ground coil(3) is connected to the ground terminal electrode. |
