The purpose of the present invention is to provide a method for manufacturing a reinforced composite material that can be carried out at low cost and that can also utilize the properties of fibers as they are to exhibit excellent strength. In order to achieve this purpose, reinforcing fibers are press-molded with a predetermined gap in the matrix using an upper die while maintaining tension, and then the reinforcing fibers are press-molded with a predetermined gap between the press-molded fibers and the upper die. The base material is injected into the base material, and the injected base material is allowed to infiltrate and fill the space between the fiber and the matrix through the fibers, thereby casting the base material on both the front and back sides of the fibers.
