PROBLEM TO BE SOLVED: To provide a nonwoven fabric for reinforcing a FRP, not requiring release paper when preserving the fabric, having strength and stiffness required and sufficient for application operation, and having excellent uniformity. SOLUTION: The nonwoven fabric for reinforcing the FRP includes at least a main fiber and a binder fiber, and the binder fiber is a core-sheath binder fiber using a polyethylene terephthalate as the core and a modified polyethylene terephthalate having a melting point lower than that of the core part as the sheath. The nonwoven fabric preferably contains an acrylic resin or a styrene-acrylic resin. The content of the acrylic resin is 1-7 mass% based on the amount of nonwoven fabric, and the content of the core-sheath binder fiber is 5-20 mass% in the nonwoven fabric for reinforcing the FRP.
