Steel Cord for Tire Belt Ply Reinforcement

A steel cord for tire belt ply reinforcement includes a cord formed by periodically twisting n wires, wherein the n wires are compressed by rolling, and at least one of the n wires is compressed into a non-circular shape, when n is an odd number, a cross-section of one wire from among the n wires is circular due to rolling, and cross-sections of n−1 wires from among the n wires are non-circular, and when n is an even number, cross-sections of two wires from among the n wires are circular due to rolling, and cross-sections of n−2 wires from among the n wires are non-circular due to rolling.
