PURPOSE: To prevent respective yarns from receiving folding friction at a small radius, by constituting a woven fabric of the first group of yarns laminated in the circumferential direction of the woven fabric and the second groups of yarns arranged in a state intersecting the first group of the yarns at right angles so as to surround the first group of the yarns.

CONSTITUTION: A woven fabric (F) is constituted of two yarn groups of the first group of yarns 10 laminated in the circumferential direction thereof and the second group of yarns 24 arranged in a state intersecting the first group of the yarns 10 at right angles so as to surround the first group of the yarns 10. Thereby handling is facilitated in using fibers, such as carbon fiber, readily affected by folding friction as yarns.
