To provide a reinforcing woven fabric, which is excellent in deformability, capable of following a complicated shape and excellent in retention of the shape, and a preform using it, a fiber reinforced plastic molded component and a process for producing them. Provided is a reinforcing woven fabric where a resin material is stuck on at least one surface of a fabric substrate containing a plurality of reinforcing fiber bundles, then the resin material stuck over two or more reinforcing fiber bundles is peeled from a part of the two or more reinforcing fiber bundles by varying the relative position of a plurality of reinforcing fiber bundles constituting the fabric substrate, wherein the maximum value of load till a tensile strain in a non fiber axial tensile test reaches 1% is in a range of 0.01 to 0.75 N.
