摘要： A multilayer ceramic electronic component including thin external terminal electrodes each having a superior bonding force to a ceramic base body is provided. In order to form the external terminal electrodes, after Cu plating films are deposited on exposed portions of internal electrodes by direct plating on a ceramic base body, a Cu liquid phase, an O2-containing liquid phase, and a Cu solid phase are generated between the Cu plating film and the ceramic base body by a heat treatment, so that Cu oxides are dispersed in the Cu plating film, at least near an interface with the ceramic base body. Since the Cu oxides function as an adhesive, a bonding force of the Cu plating film to the ceramic base body can be increased, and hence the external terminal electrode having a superior bonding force to the ceramic base body can be obtained.

摘要： In a laminated ceramic electronic component in which, by directly carrying out a plating process on an outer surface of a component main body, an external electrode is formed thereon, an attempt is made to improve the adhesion strength between a plated film forming the external electrode and the component main body. A brazing material containing Ti is applied to at least one portion of a surface on which external electrodes of a component main body is formed, and by baking this brazing material, a metal layer containing Ti is formed. Moreover, the external electrodes are formed by a plating process so as to coat at least the metal layer, and a heating process is then carried out so as to cause counter diffusion between the metal layer and the plated film that is to form the external electrodes.
