Abstract
A partially separated fiber bundle includes a separated fiber section and an unseparated fiber section, being configured to give a ratio A/Aof 1.1 or larger and 3 or smaller, when the number of fiber bundles contained in the width direction of the partially separated fiber bundle (fiber separating number: N) measured at a freely selected point P(where, n represents an integer of 1 to 100, and freely selected points Pand P, excluding n=100, being 50 cm or more away from each other), is divided by a full width of Wof the partially separated fiber bundle, to calculate the fiber separating number per unit width A, and assuming its maximum value as Aand its minimum value as A.
