Abstract

An electronic component includes an element body and an external electrode disposed on the element body. The external electrode includes an underlying metal layer, a conductive resin layer, and a plating layer. The underlying metal layer is disposed on the element body. The conductive resin layer contains a plurality of conductive fillers and is disposed on the underlying metal layer. The plating layer is disposed on the conductive resin layer. A part of the plurality of conductive fillers is sintered with the underlying metal layer and is coupled to the underlying metal layer. Another part of the plurality of conductive fillers is exposed to a surface of the conductive resin layer and is in contact with the plating layer.
