Abstract
Each sheet material is formed by arraying carbon fiber lines, each having a predetermined width, in parallel with one another. Meanwhile, an array direction of the carbon fiber lines of each sheet material is set to form an angle in a range from ±30° to ±60° to a weaving advancing direction of a stitching yarn. Moreover, a stretch ratio of the stitched base material in its lengthwise direction in a case where a load per inch width of the stitched base material is applied in the weaving advancing direction of the stitching yarn is equal to or below 4% when the load is 5 N, and is equal to or above 10% when the load is 25 N.
