To obtain both a multiaxial stitched fabric capable of simply preparing a preform and providing an inexpensive FRP having excellent resin impregnating properties and uniformity, a smooth surface and excellent mechanical characteristics and to provide a method for molding.

This reinforcing multiaxial stitched fabric is characterized by arranging a plurality of reinforcing fiber yarns parallel in the form of a sheet, composing layers, crossing and laminating at least two or more layers of the layers, forming a laminate and integrating the laminate with stitching yarns of low-melting A polymer yarns and high-melting B polymer yarns different in melting point.
