Shield member, wire harness, and method of manufacturing wire harness

1. A shield member comprising:

a metal foil layer and a base layer which have flexibility and are sheet-like or band-like;

a bonding layer which bonds the metal foil layer and the base layer;

a cylindrical portion and an overlapping portion which are made by winding and folding the metal foil layer and the base layer so that the metal foil layer is on an inside relative to the base layer, and

a plurality of tape portions fixing the overlapping portion to the cylindrical portion at predetermined intervals,

wherein a first end of the metal foil layer is coterminous with a first end of the base layer,

wherein a second end of the metal foil layer is coterminous with a second end of the base layer,

wherein the overlapping portion is in a state of being brought down and arranged along the cylindrical portion

wherein the tape portions prevent the overlapping portion from opening with respect to the cylindrical portion,

wherein one group of tape portions in the plurality of tape portions are arranged at a position corresponding to a bend of the cylindrical portion,

wherein intervals between the tape portions of the one group located at the bend are smaller than intervals of other tape portions not associated with the bend, and

wherein the cylindrical portion is loosely fitted to one or a plurality of conductive paths such that a gap is formed between the cylindrical portion and said one or the plurality of conductive paths.

2. A wire harness comprising:

the shield member according to claim 1 ; and

said one or the plurality of conductive paths which are accommodated in the cylindrical portion of the shield member.

3. The wire harness according to claim 2 , further comprising:

an exterior member provided at an outside of the shield member, or wherein the base layer of the shield member also functions as the exterior member.

4. The shield member according to claim 1 , further comprising:

a plated layer tinned to the metal foil layer, having a thickness of about 0.8 μm, and disposed more inwardly than the metal foil layer.

5. The shield member according to claim 1 , further comprising a second base layer overlapping and adhesively bonded to the base layer.

6. A method of manufacturing a wire harness comprising:

winding and folding a sheet-like member or a band-like member which is flexible and includes a metal foil layer, a base layer, and a bonding layer that bonds the metal foil layer and the base layer around one or a plurality of conductive paths so that the metal foil layer is on an inside relative to the base layer such that a first end of the metal foil layer is coterminous with a first end of the base layer, and a second end of the metal foil layer is coterminous with a second end of the base layer; and

among a cylindrical portion and an overlapping portion which are made by the winding and folding, bringing down the overlapping portion so as to be arranged along the cylindrical portion and fixing the overlapping portion to the cylindrical portion at predetermined intervals by a plurality of tape portions, wherein

the tape portions prevent the state that the overlapping portion from opening with respect to the cylindrical portion,

one group of tape portions in the plurality of tape portions are arranged at a position corresponding to a bending point of the cylindrical portion,

intervals between the tape portions of the one group located at the bend are smaller than intervals of the other tape portions not associated with the bend, and

the cylindrical portion is loosely fitted to one or a plurality of conductive paths such that a gap is formed between the cylindrical portion and said one or the plurality of conductive paths.
