  • Patent number: 6576497
    Abstract: A ceramic substrate having two side surfaces in a lengthwise direction and two side surfaces in a widthwise direction intersecting each other. The ceramic substrate also includes at least one flat surface in a thicknesswise direction. Internal electrode films are embedded in the ceramic substrate with film surfaces thereof extending roughly parallel to the flat surface of the ceramic substrate. External electrodes are each provided on the flat surface of the ceramic substrate toward one of the two ends of the ceramic substrate in the lengthwise direction, are electrically continuous with the internal electrode films and are formed over distances and from the two side surfaces in the widthwise direction.
    Type: Grant
    Filed: December 14, 2001
    Date of Patent: June 10, 2003
    Assignee: TDK Corporation

  • Publication number: 20020070442
    Abstract: A ceramic substrate (1) has two side surfaces (64, 65) in a lengthwise direction (X) and two side surfaces (66, 67) in a widthwise direction Y intersecting each other, and is also provided with at least one flat surface (68) in a thicknesswise direction (Z). Internal electrode films (2 to 11) are embedded in the ceramic substrate (1) with film surfaces thereof extending roughly parallel to the flat surface (68) of the ceramic substrate (1). External electrodes (44, 55) are each provided on the flat surface (68) of the ceramic substrate (1) toward one of the two ends of the ceramic substrate (1) in the lengthwise direction (X), are electrically continuous with the internal electrode films (2 to 11) and are formed over distances (d11, d12) and (d21, d22) from the two side surfaces (66, 67) in the widthwise direction (Y).
