And a porous substrate mainly composed of polyolefin-based resin, laminated on at least one surface of the porous base material, comprising a porous layer containing a poly-vinylidene fluoride resin, a diethyl dropped onto the porous substrate carbonate the decrease rate is 15 seconds / mg to about 21 seconds / mg, and was dropped on the porous substrate, and the spot diameter of diethyl carbonate in 10 seconds or more 20mm, also in the above poly-vinylidene fluoride resin, , the non-aqueous electrolyte secondary battery separator comprising a laminated body, characterized in that the content of the α-type crystal at least 36 mol% in the case where the total content of the α-form crystal and β-form crystal is 100 mol%, the occurrence of curl a it can be suppressed.
