Title:
SHIELD CONDUCTIVE PATH
Document Type and Number:
WIPO Patent Application WO/2017/014017
Kind Code:
A1
Abstract:
The present invention enables a shield function to be obtained over wide frequency bands from low frequencies to high frequencies even when the cross sectional area of a shield member is small.
A shield conductive path (A) is provided with: a conductive path body (12u, 12v, 12w); an insulating layer (13u, 13v, 13w) enclosing the conductive path body (12u, 12v, 12w); and a shield member (15u, 15v, 15w) which is provided so as to oppose an outer peripheral surface of the insulating layer (13u, 13v, 13w), and which is constructed of a laminate of a conductive layer (17) and a magnetic material layer (20). Electromagnetic noise from low to intermediate frequency bands can be shielded by the conductive layer (17), and electromagnetic noise from intermediate to high frequency bands can be shielded by the magnetic material layer (20). Because different frequency regions are assigned to the conductive layer (17) and the magnetic material layer (20), neither the conductive layer (17) nor the magnetic material layer (20) need to have the cross sectional areas thereof increased more than is necessary.
