摘要： The invention provides a porous film comprising aromatic polyamide as a constituent component that has high heat resistance, high air permeability and high affinity to electrolytes. It is a porous aromatic polyamide film comprising aromatic polyamide and a hydrophilic polymer wherein the hydrophilic polymer accounts for 12 to 50 parts by mass per 100 parts by mass of the aromatic polyamide, the thickness being 2 to 30 micrometers, the Gurley air permeability being 0.5 to 300 seconds/100 ml, and the thermal shrinkage rate being -0.5 to 1.0% at 200°C.

摘要： An aromatic polyamide porous film that excels in thin-film forming capability and can easily express stable porous characteristics even after use at high temperature for a prolonged period of time. There is provided an aromatic polyamide porous film consisting of a porous film composed mainly of an aromatic polyamide, characterized in that on at least one major surface thereof, when the range of section area S μm2 is measured by means of an atomic force microscope, the section area at a depth of 10 nm from the top surface, S(10) μm2, and the section area at a depth of 20 nm from the top surface, S(20) μm2, simultaneously satisfy the relationships: 0.01≤S(10)/S≤0.3, and 5≤S(20)/S(10)≤20.
