摘要：PROBLEM TO BE SOLVED: To provide a continuous multi-axial reinforcing fiber sheet which is characterized in that the reinforcing fiber is arranged in an optional angle to a main axis; the sheet can be adequately used for draw molding without the loosening of the reinforcing fiber; and a long-length fiber-reinforced plastic structure with significantly enhanced torsional rigidity can be manufactured with the sheet, and a method for manufacturing the multi-axial reinforcing fiber sheet. SOLUTION: The method comprises a step wherein a large number of reinforcing fiber sheet segments 10(10A1, 10A2 to 10B1, 10B2, etc.) formed of the reinforcing fiber (f) arranged in a resin-permeable support sheet 12, are drawn up in order along the longitudinal axis of the multi-axial reinforcing fiber sheet 20 in the way that the orientation angle of the reinforcing fiber (f) is angled (αandβ) as specified to the longitudinal axis of the multi-axial reinforcing fiber sheet (20); and a step wherein the reinforcing fiber sheet segments 10(10A1, 10A2 to 10B1, 10B2, etc.) are stitched S in the longitudinal axis direction.
