Abstract: A steel cord for reinforcing a rubber article and a pneumatic tire. When it is used as a reinforcement material for a tire belt, the steel cord is capable of satisfying weight lightening, durability, and driving stability. The steel cord is constructed from a core made by parallelly arranging two non-twisted core wires (1) and from one layer of sheath made by twisting 3 to 5 sheath wires (2) around the core. The outline shape of the cord in a cross-section orthogonal to the axis of the cord is flat. The inclination, as seen from the side of the cord, of the core wires is 3° or less relative to the cord axis.
