ABSTRACT:
A noise filter for suppressing radiation noises leaking from a signal transmission cable and comprising combination of flat cable segments with a magnetic material core, the magnetic material core being provided with a pair of slits extending in parallel to each other, the flat cable segments each being bent in a U-like shape and inserted at both ends into the slits, so that a noise filter is formed of the magnetic material core fixed to the flat cable segments and both ends of each flat cable segment projecting from one side surface of the magnetic material core are connected to a printed substrate or the like, whereby the flat cable segments as a whole serve as a common mode coil to suppress leakage of noise.
