The present invention provides a steel cord comprising one core steel filament and n sheath steel filaments, wherein the core steel filament is untwisted, the sheath steel filaments are twisted aroundthe core steel filament, the core steel filament is substantially linear in the longitudinal direction, the core steel filament is a flat filament, the aspect ratio of width to thickness on the cross-section of the core steel filament is in the range of 1.08 to 1.90. When the steel cord is embedded into a rubber layer used for manufacturing a tire, the problem of end warping of the steel cord isreduced.
