Provided is a biaxially oriented polyamide film which has good mechanical and thermal properties even if it is a product near the end of a calendered roll, and which has little S-shaped curl due to moisture absorption after bag making. A biaxially oriented polyamide film, characterized in that it is a biaxially oriented polyamide film comprising a polyamide resin containing 60% by mass or more of polyamide 6, the molecular orientation angle of the film is 20° or more, and the moisture absorption strain is 1.3 % or less, the impact strength is 0.8 J/15 μm or more, and the thermal shrinkage rate after heating at 160° C. for 10 minutes is 0.6 to 3.0 percent in both the MD direction and the TD direction. |
