Abstract
The present invention aims to provide a sheet-shaped reinforcing fiber substrate having shear deformability to conform to a three dimensional shape and restraining the generation of waste pieces to realize a large improve in the yield of reinforcing fibers and a reduction in production cost, and also provide a production method therefor. The sheet-shaped reinforcing fiber substrate has a layered structure containing N layers (N being an integer of 3 or more) produced by arranging a plurality of reinforcing fiber bundles with appropriate lengths and meets the requirements (1) to (5) given below:
