A steel cord includes a two-layer stranded construction including a core in which two or three core filaments are twisted, and including a one-layer outer sheath in which outer sheath filaments are helically wound around the core and along a longitudinal direction of the core. The core filaments have same filament diameters as the outer sheath filaments, length of lay for the core is same as length of lay for the outer sheath, and length of lay/filament diameter, which indicates a ratio of length of lay to a filament diameter, is between 50 and 75. Two or more filaments selected from among the core filaments and the outer sheath filaments, are crimped filaments each including bent sections and non-bent sections that are repeatedly disposed along the longitudinal direction.
