The present invention provides a porous film having practically sufficient mechanical strength and excellent in ion permeability. Disclosed is a porous film made of thermoplastic resin having micropores, wherein the micropore are formed from a 3-dimensional network made of trunk fibrils extending in one direction of the film and branch fibrils through which the trunk fibrils are connected to one another, and the density of the branch fibrils formed is higher than the density of the trunk fibrils formed, and the average pore diameter d (µm) of the micropores as determined by a bubble-point method (ASTM F316-86) and the average pore radius r (µm) of the micropores as determined by mercury porosimetry (JIS K1150) satisfy the relationship 1.20~2 r/d ~1.70.
