Abstract
Official abstract text for this publication.
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.

What is claimed is: 1. A ceramic electronic component having an outer dimension of a length not smaller than about 0.57 mm and not greater than about 0.65 mm, a width not smaller than about 0.27 mm and not greater than about 0.35 mm, and a thickness not smaller than about 0.27 mm and not greater than about 0.35 mm, the ceramic electronic component comprising: 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; wherein 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; and a volume occupied by the resin component in the inner external electrode is not lower than about 3.79×10 −7 ml and not higher than about 1.02×10 −6 ml. 2. A ceramic electronic component having an outer dimension of a length not smaller than about 0.95 mm and not greater than about 1.20 mm, a width not smaller than about 0.45 mm and not greater than about 0.70 mm, and a thickness not smaller than about 0.45 mm and not greater than about 0.70 mm, the ceramic electronic component comprising: 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; wherein 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; and a volume occupied by the resin component in the inner external electrode is not lower than about 5.23×10 −7 ml and not higher than about 2.53×10 −6 ml. 3. A ceramic electronic component having an outer dimension of a length not smaller than about 1.5 mm and not greater than about 1.8 mm, a width not smaller than about 0.7 mm and not greater than about 1.0 mm, and a thickness not smaller than about 0.7 mm and not greater than about 1.0 mm, the ceramic electronic component comprising: 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; wherein 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; and a volume occupied by the resin component in the inner external electrode is not lower than about 1.94×10 −6 ml and not higher than about 2.84×10 −6 ml. 4. The ceramic electronic component according to claim 1 , wherein the metal component of the inner external electrode includes a first metal component and a second metal component higher in melting point than the first metal component. 5. The ceramic electronic component according to claim 4 , wherein the first metal component is Sn. 6. The ceramic electronic component according to claim 4 , wherein the second metal component is Ag or Cu. 7. The ceramic electronic component according to claim 1 , wherein the metal component of the outer external electrode is Ni.
