摘要：
The present invention relates to a reactive polymer layer-supported porous film for battery separator, including: a porous film substrate; and a reactive polymer layer supported on the porous film substrate, the reactive polymer layer having a thickness of 2 μm or less and being obtained by a crosslinking reaction between a polyfunctional isocyanate and a crosslinkable polymer having both a reactive group capable of reacting with an isocyanate group and a cationically polymerizable functional group in the molecule thereof, in which the reactive polymer layer has a plurality of through-holes having an average pore diameter of 5 μm or less.
