Claim 0:
1. An electronic component comprising:
an element body that includes a dielectric and at least one inner electrode; and
at least one external electrode,
wherein each of the at least one external electrode includes:
a base layer connected to one or more of said at least one inner electrode and containing a metal and a first co-material mixed with the metal, the base layer being formed on a side surface of the element body and extending from the side surface to cover one or more of adjacent surfaces of the element body, the base layer thereby having a plurality of faces facing different directions,
a plating layer formed on at least one face of the base layer, and
an oxide layer formed on one or more of the faces of the base layer other than said at least one face of the base layer, the oxide layer having a surface layer made of plural kinds of oxides, the plural kinds of oxides including an oxide film of the metal of the base layer and an oxide ceramic, the oxide ceramic being distributed in the form of islands over an entire surface of the oxide layer, being exposed on the surface of the oxide layer, and puncturing the oxide film to reach the base layer, thereby serving as a strut penetrating the oxide layer and supporting the oxide layer on the base layer.
