    Abstract: A steel cord for the reinforcement of rubber articles has a two-layer construction in which a core consists of two steel filaments and a sheath arranged around the core consists of nine steel filaments. Preferably the two steel filaments constituting the core are either non-twisted filaments or are twisted at a pitch of not less than 30 mm on average, a ratio (ds/dc) of the diameter ds of each steel filament constituting the sheath to the diameter dc of each steel filament constituting the core is within a range of 35-80%, and a ratio (a/b) of the minor diameter a to the major diameter b of the cord cross-section in an arbitrary position in the longitudinal direction of the cord is within a range of 63-100%
