PROBLEM TO BE SOLVED: To obtain a film excellent in transparency, flex fatigue resistance, and dimensional stability against water by using a composition based on an aromatic polyamide resin comprising terephthalic acid and/or isophthalic acid and a specified aliphatic diamine and containing a specified amount of a flex fatigue resistance improver. SOLUTION: This film is made from a polyamide resin composition based on an aromatic polyamide resin comprising terephthalic acid and/or isophthalic acid and a 6-12C aliphatic diamine, containing 49.8-99.8 wt.% this resin and 0.2-10.0 wt.% flex fatigue resistance improver. This composition may additionally contain at most 50.0 wt.% aliphatic polyamide resin, desirably being at least one member selected among nylons-6, -12, -6.6 and -6.12, a nylon-6/6.6 copolymer, and a nylon-6/12 copolymer. The flex fatigue resistance improver used is a blocked polyesteramide elastomer or the like.
