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.

Electronic component

The monolithic ceramic electronic component includes a first external electrode, a second external electrode, and a ceramic sintered compactincluding internal electrodesand, the first and second external electrodesandbeing disposed on both end facesandof the ceramic sintered compactThe first and second external electrodesandhave a multilayer structure in which sintered electrode layersand, intermediate electroplated layersand, and plated layersandare arranged in that order. Exposed surface regionsof insulating oxidesare exposed from the outer faces of the sintered electrode layersand, the oxidesbeing derived from a glass frit contained in the sintered electrode layers. Metalsare deposited on the exposed surface regionsand the intermediate electroplated layersandare then formed by electroplating.
