Abstract

To provide a polyketone porous film having heat resistance and chemical resistance and useful as a filter for filtration having a high particle collection efficiency and as a battery or capacitor separator having a low permeation resistance to ion and the like. A polyketone porous film comprising from 10 to 100 mass % of a polyketone as a copolymer of carbon monoxide and one or more olefins, wherein the polyketone porous film has a pore formed only by a polyketone, the pore diameter uniformity parameter as a value obtained by dividing the standard deviation of the pore diameter in the pore by an average pore diameter is from 0 to 1.0, and the average through hole diameter of the polyketone porous film is from 0.01 to 50 μm.
