Abstract
A biaxially oriented polyphenylene sulfide film contains polyphenylene sulfide and polyether imide, wherein the contents of the polyphenylene sulfide and the polyether imide are 70 to 99 parts by weight and 1 to 30 parts by weight respectively when the total amount of the polyphenylene sulfide and the polyether imide is taken as 100 parts by weight, and further contains a compound having one or more groups selected from an epoxy group, an amino group and an isocyanate group as a compatibilizing agent in an amount of 0.1 to 10 parts by weight based on 100 parts by weight of the polyphenylene sulfide and polyether imide in total, and the polyether imide forms a dispersed phase with an average particle diameter of 10 to 500 nm and the biaxially oriented polyphenylene sulfide film exhibits a tensile elongation at break of 110 to 250% in both the longitudinal direction and width direction.
