ABSTRACT:
An electric noise absorber, comprising hollow cases that are shaped so as to surround the periphery of electric cable of an electronic device and are filled with a magnetic substance, such as grain ferrite, which absorbs electric noise on the electric cable. The hollow cases are molded to fit the electric cable and the quantity of magnetic substance is adjusted to reduce as much electric noise as desired. Consequently, the electric noise absorber is made easily and has no extra units.
