A porous film that is produced from a substantially nonsulfonated aromatic polyether-ketone with a crystallinity of 10 wt.% or above by the wet film forming technique and that has pores with a mean pore diameter of 0.02-30.00 mu m and a pore percentage of 7-90 % and an anisotropic structure. This film is crytalline and excellent in the resistances to heat, chemicals and hot water, water permeability, and the balance between water permeability and fractionation performance.
