PROBLEM TO BE SOLVED: To provide a steel cord which is used for reinforcing rubber articles and can reduce the cost of an installation and the cost of the production and into whose inner portion the impregnation of a rubber can be improved without deteriorating compression rigidity. SOLUTION: This steel cord has a 1×n twist structure wherein the total number n of metal filaments 6 to 12, for example a steel cord 10 having a 1×8 twist structure, is formed by spirally winding the outer peripheries of metal filaments of even numbers 2, 4, 6, 8 with other metal filaments of odd numbers 1, 3, 5, 7, respectively, and then twisting four pairs of the filament bundles 9<SB>-1</SB>to 9<SB>-4</SB>formed thus.
