Disclosed are a film for forming a composite material, which is capable of improving impregnation properties by using a carrier film on which a low viscosity resin layer is formed, and a method for manufacturing a composite material using the same. The film for forming a composite material, according to the present invention, comprises: a continuous fibrous layer; and a carrier film which is adhered to any one side of the continuous fibrous layer and has a low viscosity resin layer formed on the adhered side of the continuous fibrous layer. Thus, the present invention provides the advantage of having a composite material with excellent impregnation properties and excellent mechanical performance.
