A thermoplastic resin pre-preg characterized in comprising at least: a constituent element (I) which is 20-60 weight parts of a thermoplastic resin (A) having a linear or branched polymer structure; a constituent element (II) which is 2-10 weight parts of a thermoplastic resin (B) which is unevenly distributed to a surface site and has a lower melting point than that of the thermoplastic resin (A); and a constituent element (III) which is 30-78 weight parts of reinforcement fiber; also, a molded preform and molded composite using the same, and a method for producing a molded preform and molded composite. When thermoplastic resin pre-pregs are stacked together or when a thermoplastic pre-preg is used in insert-molding, the present invention makes it possible to efficiently enhance the surface adhesiveness of the pre-preg without causing a decline in mechanical properties, and makes it possible to ensure a desired adhesiveness during molding of the molded preform or molded composite.
