  • Publication number: 20140375175
    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.

  • Publication number: 20140239772
    Abstract: In an electronic component, when L0 is a dimension of an electronic component body in a first direction, L1 is a distance between a first outer electrode and a second outer electrode on a first surface in the first direction, and L2 is a dimension of each of the first and second outer electrodes on the first surface in the first direction, 0%<L1/L0<10% and 30%<L2/L0<50% are satisfied.

  • Publication number: 20130107421
    Abstract: A ceramic body includes an inner electrode disposed inside the ceramic body and in which an end portion of the inner electrode extends to a surface of the ceramic body. An electrode layer is formed on the surface of the ceramic body so as to cover the end portion of the inner electrode, the electrode layer including a resin, a first metal filler that contains a first metal component, and a second metal filler that contains a second metal component having a higher melting point than the first metal component. A step of heating the electrode layer is performed to form an electrode including a metal layer that is located on the surface of the ceramic body and that includes the first and second metal components and a metal contained in the inner electrode.

  • Publication number: 20130107420
    Abstract: A ceramic electronic component includes a ceramic body and an outer electrode. The outer electrode is disposed on the ceramic body. The outer electrode includes a first conductive layer and a second conductive layer. The first conductive layer includes a resin, a first metal component, and a second metal component having a higher melting point than the first metal component. The second conductive layer is disposed on the first conductive layer. The second conductive layer is includes a plating film. An alloy particle containing the first metal component and the second metal component protrudes to the second conductive layer side from a surface of the first conductive layer.

  • Publication number: 20130106560
    Abstract: A ceramic electronic component includes a ceramic body, an inner electrode, an outer electrode, and a connecting portion. The inner electrode is disposed inside the ceramic body. The end portion of the inner electrode extends to a surface of the ceramic body. The outer electrode is disposed on the surface of the ceramic body so as to cover the end portion of the inner electrode. The outer electrode includes a resin and a metal. The connecting portion is disposed so as to extend from an inside of the outer electrode to an inside of the ceramic body. In a portion of the surface of the ceramic body on which the outer electrode is disposed, the length of the connecting portion that extends in a direction in which the inner electrode is extends about 2.4 ?m or more.
