  • Patent number: 11551865
    Abstract: An electronic component includes a component body, a base electrode that has a surface exposed from the component body and contains at least one of silver and copper, an alloy layer deposited on the surface of the base electrode, and a nickel layer deposited on a surface of the alloy layer. The material of the alloy layer is an alloy containing nickel and tin.
    Type: Grant

  • Patent number: 7379288
    Abstract: The monolithic ceramic electronic component includes a first external electrode 5, a second external electrode 6, and a ceramic sintered compact 4 including internal electrodes 2 and 3, the first and second external electrodes 5 and 6 being disposed on both end faces 4a and 4b of the ceramic sintered compact 4. The first and second external electrodes 5 and 6 have a multilayer structure in which sintered electrode layers 5a and 6a, intermediate electroplated layers 5b and 6b, and plated layers 5c and 6c are arranged in that order. Exposed surface regions 7a of insulating oxides 7 are exposed from the outer faces of the sintered electrode layers 5a and 6a, the oxides 7 being derived from a glass frit contained in the sintered electrode layers. Metals 8 are deposited on the exposed surface regions 7a and the intermediate electroplated layers 5b and 6b are then formed by electroplating.
