PROBLEM TO BE SOLVED: To provide a glass fiber mat tending to elongate unidirectionally in a condition of being impregnated with a resin and having unidirectional physical properties including mechanical strength and others when the resin is cured, and to provide a method for producing the glass fiber mat. SOLUTION: This mat has the following structure: 60 wt.% or greater of glass fibers 1 accumulated in layers are oriented unidirectionally, the accumulated glass fibers 1 are sewn with yarns 2 in the direction rectangular to the oriented direction of the glass fibers 1, bound with a solvent-soluble binder, or entangled with glass fibers raised by needle punching. The other objective method for producing this mat comprises unidirectionally orienting most of the glass fibers by a specific glass fiber orientation device and accumulating them, and then sewing them, impregnating them with the binder, or subjecting them to needle punching.
