Abstract:
Provided is a shielded conductive path exhibiting a shielding function over a broad frequency band between a low frequency and a high frequency even when the shielding member has a small cross-sectional area. A shielded conductive path includes conductive path main bodies, insulating layers surrounding the conductive path main bodies, and shielding members facing the outer circumferential surfaces of the insulating layers, each have a configuration in which a conductive layer and a magnetic layer are layered together. Electromagnetic noise in a frequency band between a low frequency and an intermediate frequency is blocked with the conductive layer, and electromagnetic noise in a frequency band between an intermediate frequency and a high frequency is blocked with the magnetic layer. The different frequency regions are assigned to the conductive layer and the magnetic layer, and therefore, the cross-sectional areas of the conductive layer and the magnetic layer need not be increased.
