  • Patent number: 10622149
    Abstract: A method for producing an electronic component including a body and first and second external electrodes arranged on an external surface of the body. An edge portion of the first external electrode and an edge portion of the second external electrode face each other on the body. The first and second external electrodes each include a copper-metal-containing layer and a protective copper oxide layer covering the copper-metal-containing layer within the edge portion of the first and second external electrodes, respectively.

  • Patent number: 9530565
    Abstract: An electronic component has dimensions (length×width×thickness) of about 0.6 mm to about 1.0 mm×about 0.3 mm to about 0.5 mm×about 0.07 mm to about 0.15 mm. An area of a triangle defined by a first hypothetical straight line being in contact with the top of a portion of an outer electrode positioned on a first main surface at a center in the width direction and extending in the length direction, a second hypothetical straight line being in contact with the top of a portion of the outer electrode positioned on the first end surface at the center in the width direction and extending in the thickness direction, and a third hypothetical straight line being in contact with the outer electrode at the center in the width direction and being inclined at about 45° with respect to the first and second hypothetical straight lines is about 450 ?m2 or larger.

  • Patent number: 9148954
    Abstract: A ceramic electronic component includes a ceramic body and an outer electrode. The ceramic body includes first and second principal surfaces, first and second lateral surfaces, and first and second end surfaces. The outer electrode is provided on the first principal surface. The outer electrode includes an underlying electrode layer containing Cu and glass, and a Cu plating layer. The underlying electrode layer is disposed on the first principal surface. The Cu plating layer is disposed on the underlying electrode layer. The Cu plating layer is thicker than the underlying electrode layer.
