Abstract
A biaxially oriented polyarylene sulfide film made of a polyarylene sulfide resin composition has a melt crystallization temperature of not lower than 160° C. and not higher than 220° C. The biaxially oriented polyarylene sulfide film contains 70 to 99 parts by weight of the polyarylene sulfide and 1 to 30 parts by weight of thermoplastic resin A; the thermoplastic resin A constitutes a dispersed phase having an average dispersion diameter of 50 nm to 500 nm. The biaxially oriented polyarylene sulfide film has a breaking stress at 200° C. in the machine direction and/or transverse direction of not less than 30 MPa and not more than 90 MPa and has an elongation at break at 200° C. in the machine direction and/or transverse direction of not less than 100% and not more than 250%.
