摘要： Biaxially-oriented nylon film according to the present invention is biaxially-oriented nylon film made from nylon (6). In the biaxially-oriented nylon film, an elongation ratio of the film measured in a tensile test in each of a direction in which the film is moved, a direction of a film width a 45 degree direction and a 135 degree direction until a film rupture is 70 percent or more, the elongation ratio being measured under conditions of: a sample width being 15mm; a distance between gauge points being 50mm; and a tensile speed being 100mm/min., and a stress ratio A (σ 1 /σ 2 ) between a tensile stress σ 1 and a tensile stress σ 2 in a stress-strain curve obtained in the tensile test of the film is 2 or more in each of the four directions, the tensile stress σ 1 being a value at a point where the elongation ratio becomes 50 percent while the tensile stress σ 2 being a value at an yield point.
