PROBLEM TO BE SOLVED: To provide a drop optical fiber cable which is light weighted and can be made to have a small diameter. SOLUTION: The drop optical fiber cable 1 is provided with coated optical fibers 2 and 3, a resin-coated tension member 6, and a supporting wire 7. The resin-coated tension member 6 is formed in a circular cross section in which a tension member 4 made of a fiber-reinforced thermosetting resin coated with a coating layer 5 made of a thermoplastic resin, and a pair of coated tension members 6 are coaxially arranged above and below the coated optical fibers 2 and 3 with a predetermined space interposing the coated optical fibers. The supporting wire 7 is arranged above the coated tension member 6, and the coated optical fibers 2 and 3, coated tension member 6 and the supporting wire 7 have a structure integrally coated with a main body coating part 8 made of a thermoplastic resin. The coated tension member 6 is made of an FRP high tensile body 4 having a coated layer 5 made of a thermoplastic resin. In this case, the outer periphery of the FRP tension member 4 and the inner periphery of the coating layer 5 are mutually anchor-adhered. The thermoplastic resin used for the coating layer 5 is selected from among resins which are mutually soluble with the resin used for the main body coating part 8. COPYRIGHT: (C)2004,JPO
