Abstract
A metal cord for reinforcing a rubber article is made by twisting three or more metal filaments. At least one or at most the total number minus two of the metal filaments have a larger shaping ratio in the diametrical direction of the cord than the other metal filaments. At least one of the metal filaments having a larger shaping ratio is kept out of contact at portions in the longitudinal direction with a metal filament or filaments arranged in juxtaposition at one side or both sides thereof. At least two adjacent ones of the metal filaments having a smaller shaping ratio are in contact with each other.
