PROBLEM TO BE SOLVED: To prevent a coated optical fiber from remaining inside a cable jacket in tearing off the cable jacket in an optical fiber cable composed by housing two or more cores of coated optical fibers inside the cable jacket. SOLUTION: The optical fiber cable 1 comprises a coated optical fiber bundle 3 composed of the plurality of coated optical fibers, two high-tensile wires 4 disposed roughly in parallel holding the coated optical fiber bundle 3 there between, and the cable jacket 2 for integrally covering the coated optical fiber bundle 3 and the two high-tensile wires 4, and tear notches 7 are formed holding the coated optical fiber bundle 3 there between in the axial direction of the cable jacket 2. The coated optical fiber bundle 3 is arranged so that the plurality of coated optical fibers are asymmetrical to a line segment (XX') connecting the centers of the two high-tensile wires 4. The tear notches 7 are provided with cuts 8 toward the coated optical fibers 3a and 3b arranged near the high-tensile wires 4 and arranged closest to the tear notches 7 among the coated optical fibers constituting the coated optical fiber bundle 3.
