Abstract
A biaxially oriented polyarylene sulfide film which has an excellent elongation at break and flatness is provided. The biaxially oriented film may be a biaxially oriented polyarylene sulfide film which is substantially composed of a polyarylene sulfide resin (A), wherein one of the elongations at break in the machine direction and in the transverse direction of the film is not lower than 110%; one of the breaking stresses in the machine direction and in the transverse direction of the film of the film is not higher than 200 MPa; and both of the heat shrinkage ratio in the machine direction of the film and that in the transverse direction of the film at 260° C. for 10 minutes are not less than 0% and not more than 10%.
