Abstract

An object of the present invention is to provide a polyolefin fine porous membrane having excellent pin puncture strength and air permeation resistance and having an excellent appearance without wrinkles or winding deviation when formed into a roll; a roll thereof; and a production method for a polyolefin fine porous membrane. The present invention provides a polyolefin fine porous membrane having a pin puncture strength of not less than 400 gf when calculated for a thickness of 16 ?m, an air permeation resistance of from 100 to 400 sec/100 cc when calculated for a thickness of 16 ?m, and a coefficient of static friction of from 0.5 to 1.0 when the front and back of the membrane are superimposed.
