PROBLEM TO BE SOLVED: To provide a noise current absorber which is disposed around an electric wire to absorb noises penetrating into the electric wire from outside and capable of efficiently removing noises in a high-frequency range without increasing a magnetic material in size. SOLUTION: This noise current absorber 2a is composed of a cylindrical ferrite core 6a and a loop-like conductor 8a disposed spreading over the inner and outer surface of the ferrite core 6a. By this setup, the noise current absorber 2a is capable of displaying its frequency characteristics more excellent than usual.
