PROBLEM TO BE SOLVED: To provide a manufacturing method reducing the adhesion of oligomer by preventing agglutination of a low molecular weight material to a tenter clip in manufacturing a biaxially oriented plastic film. SOLUTION: The method for manufacturing the biaxially oriented plastic film using a tenter for carrying out stretching at least in one direction includes setting the surface temperature T1 of a part not in contact with a film of the tenter clip to 75°C or higher, and setting the surface temperature T2 of a film grip part of the tenter clip to Tg + 35°C or lower in the biaxially oriented plastic film.
