  • Patent number: 6069786
    Abstract: In a laminated capacitor, internal electrodes formed within a naked laminated body oppose a trimming electrode formed on a surface of the naked laminated body so as to obtain an electrostatic capacity, and the internal electrodes differ from one another in area opposed to the trimming electrode. By removing the trimming electrode from a portion where it is opposed to more of the internal electrodes toward another portion where it is opposed to less of the internal electrodes, the rate of decrease in electrostatic capacity with respect to the area of the trimming electrode is large at an initial stage of the trimming process and it gradually reduces in accordance with the progress thereof. Further, when the electrostatic capacity becomes to small through too much trimming, an adjusting layer between the trimming electrode and the internal electrode is deoxidized in a part thereof so that the portion of the adjusting layer is turned conductive to increase the electrostatic capacity thereof.
