  "textContent": "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.",
