PCT No. PCT/JP89/00130 Sec. 371 Date Jul. 6, 1989 Sec. 102(e) Date Jul. 6, 1989 PCT Filed Feb. 9, 1990 PCT Pub. No. WO88/07779 PCT Pub. Date Aug. 24, 1989.The present invention relates to an optical fiber cable. In view of narrowing optical fiber cables, the spiral grooves to accommodate optical fiber cables are formed in the core loading material, in the longitudinal direction, by bundling high tensile strength synthetic resin fibers and covering the external circumference of the bundled material with a synthetic resin covering layer. Moreover, a method is disclosed for manufacturing an optical fiber cable which stably loads the optical fibers by holding the core loading material in order to eliminate deviation generated in the rotating direction around the core loading material on the occasion of loading fibers in the spiral grooves of core loading material.
