In a ceramic electronic component having a thin structure, the occurrence of cracks due to stress applied when the ceramic component is being mounted or in a mounted state are prevented. Each of first and second external terminal electrodes has a substantially rectangular region on a principal surface of a ceramic element body, the principal surface being directed to the mounting surface side. An end of the first external terminal electrode, which is arranged in contact with a gap region, and an end of the second external terminal electrode, which is positioned in contact with the gap region, each preferably have a concave-convex shape on the principal surface.

摘要:
A method of manufacturing a ceramic electronic component prevents variations in characteristics even when the ceramic electronic component is embedded in a wiring board. Ceramic green sheets containing an organic binder having a degree of polymerization in a range from about 1000 to about 1500 are prepared. A first conductive paste layer is formed on a surface of each of the ceramic green sheets. The ceramic green sheets are laminated to form a raw ceramic laminated body. A second conductive paste layer is formed on a surface of the raw ceramic laminated body. The raw ceramic laminated body formed with the second conductive paste layer is fired.
