    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. The inner external electrode includes a plurality of holes. An average opening diameter of the plurality of holes is not greater than about 2.5 μm. Some or all of the plurality of holes are embedded with the metal component of the outer external electrode.

    Abstract: A ceramic electronic component includes a rectangular or substantially rectangular parallelepiped shaped laminate in which a ceramic layer and an internal electrode are alternately laminated and an external electrode provided on a portion of a surface of the laminate and electrically connected to the internal electrode. The external electrode includes an inner external electrode covering a portion of the surface of the laminate 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. The inner external electrode includes, as a metal component, a first metal component of which a portion forms an alloy with the internal electrode so as to connect the internal electrode and the inner external electrode to each other, and a second metal component higher in melting point than the first metal component, of which a portion forms an alloy with the first metal component so as to connect the inner external electrode and the outer external electrode to each other. A concentration of a metal in a surface layer of the inner external electrode is not lower than about 17%.
