PROBLEM TO BE SOLVED: To provide an optical cable which substantially prevents the occurrence of a spacer fall in S-Z inversion parts and S-Z shift parts and has an excellent transmission characteristic and the taking out property of optical fibers and spacers for this optical cable. SOLUTION: The optical cable 1 has the spacers 10 having fiber housing parts 10a for housing coated fiber ribbons 5 and a columnar member 2 to be twisted around with the spacers 10. The spacers 10 are assembled to S-Z twists in the state of bringing their bases into contact with the columnar member 2. The bending rigidity in the depth direction of the spacers 10 is smaller than the bending rigidity in a transverse direction. The spacers satisfy U1 -U2
