An optical fiber cable 1 includes: a cable core 9 formed by stranding a plurality of loose tubes 7, each housing at least one optical fiber 5, on the periphery of a centered tension member 3; and a sheath 11 disposed on the outer periphery of the cable core 9. The sheath 11 includes: a first sheath portion 13 in which the sheath is embedded in between each of the loose tubes 7; and a second sheath portion 15, in which the sheath 11 is circumscribed around the cable core 9, to be thereby formed in a pipe shape. The first sheath portion 13 and the second sheath portion 15 are alternately positioned over the entire length of the cable core 9. |
