An inductance element comprises a coil having a hollow portion opened at both ends and provided with a winding of which number of turns (N) per length 10 mm is 20 or more and 500 or less, and a core having a single layer or a plurality of layers of magnetic ribbon of a thickness of 4 μm or more and 50 μm or less and a width of 2 mm or more and 40 mm or less, at least part thereof being disposed in the hollow portion. In such an inductance element, a ratio (N/n) of a number of turns (N) of the coil per length 10 mm to a number of layers (n) of the magnetic ribbon is set at 20 or more and 500 or less. The magnetic ribbon, for instance in a state disposed in the hollow portion of the coil, has an open magnetic circuit structure. Instead, the magnetic ribbon, by disposing penetrating the hollow portion and magnetically connecting both ends thereof, forms a closed magnetic circuit loop. Such an inductance element possesses excellent inductance characteristics and is good in winding efficiency.
