Abstract
An inductance element () comprises a core () having a multilayer body () composed of magnetic alloy thin ribbons () and an insulating coating layer () which covers the peripheral surface of the multilayer body without being bonded thereto, and a coil () wound around the core (). The magnetic alloy thin ribbons () are stacked in a non-adhered state or with a flexible insulating adhesive layer therebetween. Having such a structure, the inductance element can stably attain good characteristics even when it is small-sized or made short.
