Abstract
In order to accommodate increasing operation speed of a digital circuit, a distributed constant type noise filter having a low impedance transmission line optimal to provide a power de-coupling of an LSI operating at high speed is provided. Particularly, a capacitor-forming portion of the distributed constant type noise filter is constructed with a solid electrolytic capacitor having a 3-terminal structure. In the distributed constant type noise filter constructed as mentioned, a ratio of width W of the capacitor-forming portion to thickness d of a dielectric member thereof and length L of the capacitor-forming portion are set on the basis of dielectric constant of the capacitor-forming portion such that electric noise generated by an electron device connected thereto are removed over a wide frequency range thereof.
