  • Patent number: 10283273
    Abstract: A ceramic electronic component includes a rectangular or substantially rectangular parallelepiped-shaped stack in which a ceramic layer and an internal electrode are alternately stacked and an external electrode provided on a portion of a surface of the stack and electrically connected to the internal electrode. The external electrode includes an inner external electrode covering a portion of the surface of the stack and including a mixture of a resin component and a metal component and an outer external electrode covering the inner external electrode and including a metal component. A volume occupied by the resin component in the inner external electrode is within a prescribed range.
    Type: Grant
