    Abstract: A biaxially oriented polyarylene sulfide film excellent in molding processability and a laminated polyarylene sulfide sheet comprising the same can be provided by improving the tensile elongation at break of a biaxially oriented polyarylene sulfide film having excellent heat resistance, dimensional stability, electrical properties and chemical resistance. Disclosed is a biaxially oriented polyarylene sulfide film comprising polyarylene sulfide and other thermoplastic resin A different from the polyarylene sulfide, wherein the contents of the polyarylene sulfide and the thermoplastic resin A are 70 to 99 parts by weight and 1 to 30 parts by weight respectively when the total amount of the polyarylene sulfide and the thermoplastic resin A is taken as 100 parts by weight and the resin thermoplastic A forms a dispersed phase with an average particle diameter of 10 to 500 nm and the biaxially oriented polyarylene sulfide film exhibits a tensile elongation at break of 110 to 250% in at least one of the longitudinal direction and width direction and a tensile fracture elongation of 80 to 250% in the other direction.

    Abstract: A film excellent in heat resistance, dimensional stability to heat, and mechanical properties, especially a film capable of satisfying requirements such as higher strength necessary for base-film thickness reduction, improved dimensional stability to heat and improved mechanical properties in use atmospheres, and enhanced heat resistance and improved dimensional stability to heat which meet the needs of the electrical and electronic fields for size reduction and multi-function. It is obtained by incorporating transition metal oxide particles into a thermoplastic resin and forming the composition into a film which is a biaxially oriented thermoplastic film having a melting point higher than that of the thermoplastic resin used. Preferably, when the biaxially oriented thermoplastic resin film is analyzed with a differential scanning calorimeter (DSC), the difference between the peak temperature for the quantity of heat of fusion in the 1st run (melting point T1) and the peak temperature for the quantity of heat of fusion in the 2nd run (melting point T2) satisfies the following relationship. 2°C ≤ T1-T2 ≤ 30°C Alternatively, the biaxially oriented thermoplastic resin film containing transition metal oxide particles incorporated therein is regulated so as to have a coefficient of in-plane orientation of 0.120 or higher and lower than 0.280.
