り下げずに強度向上が図れる。BEST MODE FOR CARRYING OUT THE INVENTION The reason why the foil conductor of the present invention is made of a Cu-Ag alloy and its electric conductivity is specified to be 80% IACS or more is that electric signals are not transmitted well when it is less than 80% IACS. And its tensile strength is 700N /
The reason for defining the mm 2 or more and can not sufficiently withstand the external force applied during device assembly is less than 700 N / mm 2, because the bending property and fatigue property required for the foil conductor is no longer satisfied. The Ag content of the Cu-Ag alloy is appropriately selected according to the application. However, when processing from a raw material (such as a bar-shaped ingot) to a foil conductor without performing intermediate annealing, the Ag content is 0.5 wt%. If it is less than 700 N / mm 2, a tensile strength of 700 N / mm 2 or more cannot be obtained stably, and if Ag exceeds 4.5 wt%, a conductivity of 80% IACS or more cannot be obtained stably. Therefore, the content of Ag is desirably 0.5 to 4.5 wt%. However, even if Ag is contained in a large amount of about 10% by weight, the tensile strength is 780 N / mm 2 or more by performing the intermediate annealing by adjusting the number of annealing times and the annealing conditions.
A desired foil conductor having a conductivity of 80% IACS or more can be obtained. The Cu-Ag-based alloy may contain other alloy elements useful for improving properties, or may contain unavoidable impurity elements, as long as they are trace amounts. Cu-A
If the amount of oxygen in the g-based alloy is 10 ppm or less, the highly conductive Ag phase is uniformly dispersed in the form of short fibers, so that the strength can be improved without significantly lowering the conductivity.

（ｔ）の比（ｗ／ｔ）は１３〜１４が一般的である。When the foil conductor of the present invention is processed into a ribbon shape and used, its thickness (t) should be 30 μm or less, and the ratio (w / t) of width (w) to thickness (t) should be 10 or less. By doing so, the bending resistance and the fatigue resistance are improved. This is probably because when the ratio (w / t) is 10 or more, the bending stress is favorably dispersed in the width direction. The ratio (w / t) of the width (w) to the thickness (t) of the foil conductor used for the speaker cable is generally 13 to 14.

Nos. 6 to 6 have the necessary tensile strength and electrical conductivity as signal transmission cables, etc., and Nos. 3 to 6 in particular showed properties equal to or better than those of the conventional material (No. 7). No. 3 has a higher tensile strength than No. 2 having the same Ag amount. This is because in No. 3 the amount of oxygen was small and the Ag phase was more uniformly dispersed in a fibrous state. No. 2 was cast by adding excess oxygen immediately before casting.
