In the steel cord, at least one of three strands that are successively adjacent to one another or that are in mutual contact is formed of two filaments that are paired substantially parallel to each other. The direction of pairing the two filaments of each strand is substantially the same over the entire length of the cord. Each of the remaining strands is formed of a single filament.
