Abstract
A ceramic electronic component has a ceramic element assembly, external electrodes, and metal terminals. The external electrodes are arranged on the surface of the ceramic element assembly. The external electrodes contain a sintered metal. The metal terminals are electrically connected to the external electrodes, respectively. The external electrode and the metal terminal are directly diffusion-bonded by diffusion of metal in the metal terminals into the external electrodes. The above arrangement provides a ceramic electronic component having highly reliable metal particle bonding and a method for manufacturing the same.
