  Provided are a polyamide-based film having superior thickness uniformity as well as comparatively little variation in properties in four directions formed of the 0 degree direction, 45 degree direction, 90 degree direction and 135 degree direction, and a method for producing the same. The present invention relates to a polyamide-based film, wherein (1) the difference between the maximum value and minimum value of the respective stress at 5% elongation as determined by a uniaxial tensile test is 35 MPa or less in four directions formed of a specific direction from an arbitrary point in the film that is designated as 0 degrees and directions at 45 degrees, 90 degrees and 135 degrees relative to the specific direction in the clockwise direction, and (2) the difference between the maximum value and the minimum value of the respective stress at 15% elongation as determined by the uniaxial tensile test in the four directions is 40 MPa or less.
