Abstract:
The present invention relates to a biaxially stretched polypropylene film for capacitor. The biaxially stretched polypropylene film for capacitor of the present invention can suppress an increase in tan δ and a decrease in the electrostatic capacitance even when the capacitor is used at a high voltage and an elevated temperature for a long duration.
