The present invention prevents poor contact of a core and an inductor with a substrate as well as improves the strength of attachment of such core and inductor to the substrate. A core mounted on a substrate is having one or more electrode forming parts. The electrode forming parts comprise: a convex part having a peak surface that is projecting from an end surface of the core, the most projecting portion and is shaped flat and a step part formed from the outer rim of the peak surface to the end surface of the core; and an electrically conductive coating formed on the surface of the peak surface and on the surface of the step part.
