  • Patent number: 10755859
    Abstract: An element body of a rectangular parallelepiped shape includes a pair of principal surfaces opposing each other in a first direction, a pair of side surfaces opposing each other in a second direction, and a pair of end surfaces opposing each other in a third direction. An external electrode disposed on an end portion of the element body in the third direction. When viewed from the third direction, a width of the element body in the second direction is the largest at a central position in the first direction, and gradually decreases from the central portion in the first direction. When viewed from the third direction, a position in which a length from one end to another end of the conductive resin layer in the second direction is the largest is located closer to the one principal surface than the central position.

    Abstract: An electronic component includes an element body and an external electrode disposed on the element body. The external electrode includes a sintered metal layer, a conductive resin layer disposed on the sintered metal layer, and a solder plating layer arranged to constitute an outermost layer of the external electrode. A space exists in the conductive resin layer or between the conductive resin layer and the sintered metal layer. A first maximum length of the space in a thickness direction of the conductive resin layer is shorter than a second maximum length of the space in a direction orthogonal to the thickness direction of the conductive resin layer.

    Abstract: An electronic component includes an element body and an external electrode disposed on the element body. The external electrode includes a conductive resin layer, a solder plating layer arranged to constitute an outermost layer of the external electrode, and an intermediate plating layer disposed between the conductive resin layer and the solder plating layer. The intermediate plating layer has better solder leach resistance than metal contained in the conductive resin layer. An opening is formed in the intermediate plating layer. The solder plating layer is formed on the conductive resin layer through the opening.
