Zusammenfassung:	The present invention addresses the problem of providing a biaxially oriented polyarylene sulfide film having excellent thermal dimensional stability, processability, and transport characteristics. A biaxially oriented polyarylene sulfide film having a polyarylene sulfide (PAS)-based resin as a main constituent component, the biaxially oriented polyarylene sulfide film being characterized in that the melting start temperature (Tms) and the melting point (Tm), which are measured by differential scanning calorimetry (DSC) during the first operation under the conditions of a temperature rise rate of 20 DEG C/min and a sample amount of 5 mg, satisfy formula (1). (1) 20 DEG C < = Tm-Tms < = 100 DEG C. 本发明的课题是提供热尺寸稳定性、加工性、传输特性优异的双轴取向聚芳撑硫醚膜。一种双轴取向聚芳撑硫醚膜，其以聚芳撑硫醚(PAS)系树脂作为主要构成成分，通过差示扫描量热(DSC)测定，在升温速度20℃/min、试样量5mg条件下在第一次运行中测定的熔融开始温度(Tms)和熔点(Tm)满足下述式(1)。20℃≤Tm-Tms≤100℃(1)。
