<p>PROBLEM TO BE SOLVED: To provide an inductance element, which is superior in the efficiency of winding work, in which winding work is automated and insulating property and inductance characteristics are improved. SOLUTION: The inductance element is provided with a coil, having a winding wire whose number of windings (N) in length 10 mm is 20 to 500 and having a hollow part, where both ends of the winding wire are opened and a core having the magnetic thin band of a single layer or plural layers, whose thickness is 4μm to 50μm and whose width is 2 mm to 40 mm and in which at least a part of the magnetic thin band is arranged in the hollow part. A ratio (N/n) of the number of windings (N) in the coil and the number of layers (n) in the magnetic thin band is 20 to 500. The outer part of the coil is covered by an insulator.</p> |
