Claim:
1. A ceramic electronic component, comprising: a rectangular or substantially rectangular parallelepiped laminate in which a ceramic layer and an internal electrode are alternately laminated; and an external electrode located on a portion of a surface of the laminate and electrically connected to the internal electrode; wherein the external electrode includes an inner external electrode covering a portion of the surface of the laminate and includes 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; and a concentration of a metal in a surface layer of the inner external electrode is not lower than about 17.5% and not higher than about 19.7%.
