Abstract
A stacked layered core includes a core body formed from a plurality of core, plates stacked in layers, each of the core plates having a connection base section formed in a circular shape and a plurality of salient pole sections radially extending from an external peripheral surface or an internal peripheral surface of the connection base. The circular connection base section has a fixing-side peripheral surface on the opposite side of the salient pole sections. At least one retaining recessed section is provided in the fixing-side peripheral surface of the connection base section. A dielectric film may be formed over an external surface of the core body. The retaining recessed section has a depth greater than a thickness of a bump portion of the dielectric film formed in the retaining recessed section such that the bump portion of the dielectric film is contained inside the retaining recessed section.
