Abstract
A cable includes a first shield portion that includes at least one or more lines for transmitting a signal or electric power and that is provided on the outer side of the lines, a first layer that is provided in such a manner as to cover an outer circumference of the first shield portion and that includes a member that absorbs radio waves, a second shield portion that is provided on an outer side of the first layer, a second layer that is provided in such a manner as to cover an outer circumference of the second shield portion and that includes a member that absorbs radio waves, and insulating resin that covers an outer side of the second layer.
Claims12
A cable comprising:
- a first shield portion that surrounds at least one or more lines for transmitting a signal or electric power and that is provided on an outer side of the lines;
- a first layer that is provided in such a manner as to cover an outer circumference of the first shield portion and that includes resin that absorbs radio waves;
- a second shield portion that is provided on an outer side of the first layer;
- a second layer that is provided in such a manner as to cover an outer circumference of the second shield portion and that includes resin that absorbs radio waves;
- and
- insulating resin that covers an outer side of the second layer,
- wherein the resin includes a mixture of ferrite powder in resin including PVC or elastomer,
- wherein, in the resin of the first layer and the resin of the second layer, a ratio of the ferrite powder to the resin is equal to or higher than 70% but equal to or lower than 98% in weight ratio to the resin, and
- wherein the first shield portion is grounded and the second shield portion is not grounded.
