PROBLEM TO BE SOLVED: To solve the problem of the joint part being separated, when an impact is given in the conventional method for fixing a magnetic thin band in an inductance element and the inductance is reduced because the magnetic thin band becomes loose from winding. SOLUTION: This inductance element is comprised of a coil part, in which a winding whose number of windings (N) per 10 mm in length is >=20 and <=500, is formed in an insulator bobbin having flanges on both ends, and a single layer or multiple layers of magnetic thin band whose thickness is >=4μm and <=50μm and width is >=1 mm and <=40 mm, and it is provided with a core of closed magnetic circuit, in which at least a part is arranged inside the insulator bobbin and an insulation tape for fixing the magnetic thin band. The ratio (N/n) of the number of windings (N) in the coil to the number of layers (n) in the magnetic thin band is >=20 and <=500, and an angle formed by the insulation tape in the lengthwise direction and the magnetic thin band in the lengthwise direction is 60 to 120 degrees.
