  • Ceramic electronic component and method for manufacturing the same
    Patent number: 9805865
    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.
    Type: Grant
    Filed: November 2, 2011
    Date of Patent: October 31, 2017
    Assignee: MURATA MANUFACTURING CO., LTD.
    Inventors: Hideki Otsuka, Kazuhiro Yoshida, Jun Sonoyama, Yoji Itagaki, Akihiko Nakata
