Provided is an elastomer reinforcement cord which takes advantage of characteristics of a composite cord using steel filaments and a resin filament and in which a diameter (a geometrically calculated value) of the cord including only the steel filaments without resin, as calculated from a wire diameter of the steel filaments used, is substantially the same as an actual cord diameter after vulcanization. In an elastomer reinforcement cord 10 including a core and at least one sheath layer, in which metal filaments 2 and 3 and a resin filament 1 are twisted together, gaps between the metal filaments are filled with resin. The diameter of the cord is from 98 to 100.5% of the geometrically calculated value of the diameter of the cord including only the metal filaments, and a total length of gaps between the metal filaments forming an outermost sheath layer before vulcanization is 85% or less of the geometrically calculated value. In a region surrounded by connecting the center of each metal filament forming the outermost sheath layer on a cross section in a direction orthogonal to an axial direction of the cord, the ratio of a polymer material to a region other than the region occupied by the metal filaments is from 52 to 120%.
