A biaxially oriented polyarylene sulfide film and laminated polyarylene sulfide sheets of the film contain 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.
