Abstract
An intermittent tape core wire (140) of an optical fiber cable is assembled into a cable core so that in a k core wire, an l core wire, and an m core wire composed of a multi-core optical fibers continuously adjacent in the width direction of the intermittent tape core wire (140), a difference θ between a core wire twisting direction D2km of the k core wire at a bonding portion (142) connecting the k core wire and the l core wire and a core wire twisting direction D2kl of the k core wire at a bonding portion (142) connecting the k core wire and the m core wire is different from when manufactured.
