  • Patent number: 11915879
    Abstract: An electronic component includes an element body and at least one external electrode thereon. The element body has a dielectric and inner electrodes. Each external electrode includes a base layer connected to at least one the inner electrode. The base layer is formed on a plurality of surfaces of the element body and contains a metal and a first co-material mixed with the metal. Each external electrode also includes a plating layer formed on at least one face of the base layer. Each external electrode also includes an oxide layer formed on one or more faces of the base layer other than those faces of the base layer on which the plating layer is formed. The oxide layer has a surface layer made from an oxide film of the metal of the base layer and a second co-material.

  • Publication number: 20230307181
    Abstract: A multilayer ceramic capacitor includes a ceramic body and first and second external electrodes. The ceramic body has a capacitance forming portion including first and second internal electrodes and ceramic layers. Each of the first and second internal electrodes has a first region arranged along margin portions of the ceramic body and a second region arranged at inner sides of the first region. Each of the first and second internal electrodes includes a conductive component, and a continuity rate of the conductive component in a plan view as seen from the second axial direction in the first region has a first value, and a continuity rate of the conductive component in the plan view as seen from the second axial direction in the second region has a second value, the first value being greater than the second value.

  • Publication number: 20220328251
    Abstract: A ceramic electronic component includes an element body, a first external electrode, and a second external electrode. The element body includes a dielectric, at least one first internal electrode, and at least one second internal electrode laminated over the first internal electrode via the dielectric interposed therebetween. The element body has a top surface, a bottom surface, a pair of side surfaces, a first end surface, and a second end surface, thereby the element body having a generally cuboid shape. The first internal electrode is exposed on the first end surface. The second internal electrode is exposed on the second end surface. The side surfaces of the element body are concavely curved along a longitudinal direction, so that the element body has a longitudinal central part at which a width is less than a width at the end surface. The first external electrode is formed on the first end surface and electrically connected with the first internal electrode.
