    Abstract: An electronic component includes a composite body made of a composite material of resin and magnetic metal particles, an inner electrode which is provided in the composite body and which has an end surface exposed from an outer surface of the composite body, and a metal film provided on the outer surface of the composite body and on the end surface of the inner electrode. The metal film includes a first region provided on the end surface of the inner electrode and a second region which is in contact with the magnetic metal particles exposed at the outer surface of the composite body and which is provided on the outer surface of the composite body. The thickness of the first region is less than the thickness of the second region.

    Abstract: An inductor component includes a base, an inductor device disposed in the base, and an external terminal serving as a line that is disposed on the base and that is electrically coupled to the inductor device. The external terminal includes a first metal film that is in contact with the base and that is electrically conductive, a second metal film disposed on a side of the first metal film opposite to the base, the second metal film having resistance to solder leaching, and a catalytic layer disposed between the first metal film and the second metal film. The first metal film includes a pore portion adjacent to the catalytic layer.

    Abstract: A base includes a main body and a multilayer metal film disposed on the main body. The multilayer metal film includes a first metal film disposed on the main body, the first metal film having conductivity, second metal film on the first metal film and above the main body, the second metal film having resistance to solder leaching, and a third metal film on the second metal film, the third metal film having wettability. The third metal film includes an inwardly extended portion extending between the second metal film and the main body.
