PROBLEM TO BE SOLVED: To provide a barrier paper laminate which is excellent in gas-barrier and mechanical characteristics and free from the interlayer exfoliation. SOLUTION: The barrier paper laminate comprises a paper layer and a barrier layer. The barrier layer is a barrier polyester layer mainly including a layer having a multilayer structure formed by molding a molten substrate resin component containing a thermoplastic polyester resin A and a molten subordinate resin component containing a thermoplastic resin B which are molded by different extruders through a static mixer.
