A polyimide film according to the present invention satisfies Condition (1) in which a tear propagation resistance variation C.sub.H is not more than 1.0 g, and/or Condition (2) in which a swelling coefficient C.sub.R after being dipped in an alkaline solution is not more than 20.0. By satisfying these conditions, workability of the polyimide film can be improved and working defects can be effectively prevented, thereby improving productivity of each step.
