Document Type and Number:
Japanese Patent JP5589756
Kind Code:
B2
Abstract:
The present invention provides a flexible flat cable having high conductivity and high bending durability, and a method for manufacturing the same. The present invention is a flexible flat cable comprising conductors and insulating films applied over the conductors, wherein the conductor is comprised of at least one additive element selected from the group consisting of magnesium (Mg), zirconium (Zr), niobium (Nb), calcium (Ca), vanadium (V), nickel (Ni), manganese (Mn), titanium (Ti), and chromium (Cr); 2 mass-ppm or more of oxygen; and the balance being inevitable impurity and copper, wherein the conductor has such a recrystallized texture that the size of crystal grains in the inner area of the conductor is large and that of in the surface area thereof is smaller than that of the inner area, wherein both sides of the conductor are sandwiched between insulating films.
