Abstract
Provided is an elastomer reinforcement cord with improved rust resistance. An elastomer reinforcement cordincludes metal filaments and a polymer material. The elastomer reinforcement cordhas a multi-strand structure which includes: at least one core strandformed by twisting plural metal filamentsandtogether; and two or more sheath strandseach formed by twisting plural metal filamentsandtogether, the sheath strands being twisted together around the core strand. An intra-sheath-strand filling rate a, which is a ratio of the area of the polymer material with respect to an intra-sheath-strand gap region A, is 52% or higher, and an inter-strand filling rate b, which is a ratio of the area of the polymer material with respect to an inter-strand gap region B, is 75% or higher.
