  • Method for producing a ceramic electronic part
    Patent number: 6769159
    Abstract: A method for producing a ceramic electronic part includes forming a plurality of internal electrodes arranged in a ceramic sintered compact, superimposed via a ceramic layer. The free ends of the internal electrodes are formed to have a wedge-like cross-sectional shape, with the length L of the wedge and the internal thickness t of the electrode at the base of the wedge satisfying the relationship L>2t so that there is no risk of generating inter-layer peel-off or delamination in the ceramic layers.
    Type: Grant
    Filed: June 6, 2001
    Date of Patent: August 3, 2004
    Assignee: Murata Manufacturing Co., Ltd.

  • Laminated ceramic electronic component
    Patent number: 6292353
    Abstract: The present invention provides a reliable ceramic electronic component in which cracks are hardly generated in the ceramic sintered body when a heat impact is applied or even when a stress caused by bending of a printed circuit board after packaging is applied, wherein inner electrodes are disposed in the ceramic sintered body, and wherein a first and second outer electrodes are formed so as to cover the first and second end faces, the first and second outer electrodes comprising electrode cover members extending to the upper face and lower face, up to both side faces of the ceramic sintered body, and the distance e and the distance Lg satisfying the relation of 1.5×Lg≦e≦3.
