PROBLEM TO BE SOLVED: To prevent the ovipositor of insects from piercing the optical fiber inside a jacket and to maintain equivalent workability, as before, in stripping of optical fiber. SOLUTION: In an optical fiber drop cable 1, a long optical element part 9 is formed with an optical fiber 3, composed of an optical fiber or coated optical fibers, at least a pair of tension members 5 arranged in parallel across the optical fiber 3, and a jacket 7 covering the outer circumference of the optical fiber 3 and the pair of tension members 5, wherein a long cable support wire part 29 formed by covering the outer circumference of a support wire 25 with the jacket 7 is integrated with the optical element part 9. In parallel with and longitudinal to the optical fiber 3, there are formed, for the purpose of tearing the jacket 7, at least two or more gaps 37, 39, continuously and intermittently by broken line, in the direction vertical to a plane 31 through the center of the optical fiber 3 and the pair of tension members 5, and in directions directly above and directly below the optical fiber 3 inside the jacket 7.
