Summary:PURPOSE: To provide a cabtire cable capable of sufficiently resisting against a severe environment of repeated use receiving stress of twisting, bending and drawing or the like. CONSTITUTION: A flexible pipe 5 is provided in the center, and in the periphery of this flexible pipe 5, a plurality of electric conductors 1, having an insulating layer 2, are twisted together with an interposition 3, further to insert an optical fiber 7 provided along a tension member 8 to have looseness in a hollow part of the flexible pipe 5. As a result, in repeated stress of twisting, bending and drawing or the like applied to a cabtire cable, since the interposition in the periphery of the flexible pipe is burdened, these influences on the optical fiber is reduced.
