Abstract:
An inductance element comprising:a column shaped body comprising a winding region having a polygonal sectional shape; a coil wound around said body, said coil comprising a coil wire having a surface covered with an insulation coating; a first terminal electrode provided on a first end and a side surface of said body and a second terminal electrode provided at a second end and a side surface of said body, said coil being electrically connected to a portion of said first terminal electrode provided on said side surface of said body, said coil being electrically connected to a portion of said second terminal electrode provided on said side surface of said body; and a protection material provided on said body so as to cover at least a portion of said coil, the protection material having a relative dielectric constant not higher than 6.0; wherein side edges of said winding region are chamfered and, a height, a width and a length of said inductance element satisfy the following criterion, where P1 represents the height of said inductance element, P2 represents the width of the inductance element, and P3 represents the length of the inductance element: 0.4 mm1<1.2 mm, 0.4 mm2<1.2 mm, and 0.9 mm3<2.0 mm.
