PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device of an optical fiber cable, which are capable of sufficiently suppressing the degradation of transmission characteristics due to distortion of optical fibers in an optical fiber cable having an aggregate core of intermittently fixed optical fiber ribbons housed in a sheath, even when the optical fiber cable is laid at a smaller bend angle than conventional one.SOLUTION: Each of intermittently fixed optical fiber ribbons 11 constituting an aggregate core 1 is subjected to unidirectional twisting or SZ twisting, and then the respective intermittently fixed optical fiber ribbons 11 are collected to constitute the aggregate core 1, and a sheath 5 is formed on the aggregate core 1. |
