    摘要: A prepreg formed from a resin and unidirectionally aligned reinforcement fibers, characterized in that: the prepreg is sheet-shaped; the prepreg has cutouts of a depth for cutting the reinforcement fibers, and includes reinforcement fibers (A) cut by the cutouts to a length of 10 to 50 mm and reinforcement fibers (B) having a length of equal to or more than 50 % of the sheet length of the prepreg in the alignment direction of the reinforcement fibers; the surface area of a band section including the reinforcement fibers (B) in a plan view is 1.4 % to 35.0 % of the entire surface area of the prepreg in a plan view; and at least one end of the reinforcement fibers (B) is positioned at an end portion of the prepreg in the alignment direction of the reinforcement fibers.
