Abstract:
Provided is a separator for a non-aqueous secondary battery, including: a porous substrate, and a heat resistant porous layer that is provided on one side or both sides of the porous substrate, that is an aggregate of resin particles and an inorganic filler, and that satisfies the following expression (1). In expression (1), Vf is a volume proportion (% by volume) of the inorganic filler in the heat resistant porous layer, and CPVC is a critical pigment volume concentration (% by volume) of the inorganic filler. Also provided is a separator for a non-aqueous secondary battery, including: a porous substrate, a heat resistant porous layer that is provided on one side or both sides of the porous substrate, that includes a resin and an filler, and that satisfies the following expression (2), and an adhesive porous layer that is provided on both sides of a stacked body of the porous substrate and the heat resistant porous layer, and that includes an adhesive resin. In expression (2), Vf is a volume proportion (% by volume) of the filler in the heat resistant porous layer, and CPVC is a critical pigment volume concentration (% by volume) of the filler. 0.65≤Vf/CPVC≤0.99  expression (1) 0.40≤Vf/CPVC≤0.99  expression (2)

Claim (Index 7):
The separator for a non-aqueous secondary battery according to  claim 1 , wherein the filler is magnesium hydroxide or magnesium oxide.
