PROBLEM TO BE SOLVED: To provide an inductance element easily adjusting a capacitance between a coil wire and a conductor, having a larger designing flexibility, and also having stable and excellent attenuation characteristic with less variation.SOLUTION: The inductance element has: a toroidal magnetic core 2; a conductor 6 disposed along the outer circumferential surface of the toroidal magnetic core 2; and an insulation case for housing the magnetic core 2 and the conductor 6. The inductance element is formed by winding a coating conductor 8 from the outside of the insulation case, and the conductor 6 has a ground connection terminal 7 as a terminal for grounding connection which is disposed on the outer circumference of the magnetic core 2. The insulation case has a structure in which two portions such as a portion 5 above the insulation case and a portion 4 below the insulation case are engaged, a space 10 is formed surrounded by the portion 5 above the insulation case and the portion 4 below the insulation case is formed on the engaging portion, and the conductor 6 is held and fixed in the space 10. The portion 4 below the insulation case has a through hole 15, and the terminal 7 for grounding connection protrudes from the through hole 15 to the outside of the insulation case. |
