Abstract
A pre-impregnation has a ribbon-shaped tow of reinforcing fibers and a ribbon of thermoplastic resin laminated on the ribbon-shaped tow and fixed thereto at intervals, and the thermoplastic resin is allowed to uniformly impregnate into the ribbon-shaped tow under heat application so that a void does not take place in the ribbon-shaped tow.
