  • Patent number: 8773840
    Abstract: An electronic component includes a ceramic sintered body, and a plurality of first and second inner electrodes alternately arranged inside the ceramic sintered body to be opposed to each other in a third direction with a ceramic layer interposed between the adjacent first and second inner electrodes. The first and second inner electrodes are each arranged to be exposed to a third or fourth surface without being exposed to fifth and sixth surfaces. Heterogeneous regions, which include solid solutions of metals included in the first and second inner electrodes and the ceramic sintered body, are arranged continuously in opposite end portions of the ceramic sintered body in a first direction to extend from one side end to an opposite side end of a region where the first and second inner electrodes are disposed in a third direction.

  • Publication number: 20140063687
    Abstract: An electronic component with terminal strips joined to end faces of external electrodes via a solder is characterized in that two plate-like supports of each terminal strip are formed by bending two plate-like parts projecting outward in a line-symmetrical manner from both side edges of a plate-like leg in the width direction such that at least tips of the thickness surfaces on the electronic component sides of the two plate-like parts are positioned below an external electrode of the electronic component, and the electronic component is supported from below by the tips of the thickness surfaces on the electronic component sides of the four plate-like supports. Slipping of the electronic component from both terminal strips due to melting of the solder can be suppressed in a reliable manner.
