Abstract:
1. A biaxially oriented polyarylene sulfide film composed of polyarylene sulfide resin (A) comprising polyarylene sulfide resin in an amount of not less than 95.5 wt % excluding inorganic components, 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 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 250° C. for 10 minutes are not less than 0% and not more than 10%, wherein a small endothermic peak immediately below the melting point in DSC of the film is not less than 250° C.
