Separator for non-aqueous secondary battery and non-aqueous secondary battery

A separator for a non-aqueous secondary battery, the separator comprising:

• a porous substrate;
• a heat-resistant porous layer that is provided on one side or on both sides of the porous substrate, and that contains a binder resin and inorganic particles, the inorganic particles having an average primary particle diameter from 0.01 μm to less than 0.45 μm;
• and
• an adhesive layer that is provided on one side or on both sides of a laminated body of the porous substrate and the heat-resistant porous layer, the adhesive layer comprising a plurality of adhesive resin particles adhered to the laminated body,
• wherein the adhesive resin particles include particles containing a polyvinylidene fluoride type resin, a fluorine-based rubber, an acrylic type resin, a styrene-butadiene copolymer, a homopolymer or a copolymer of a vinyl nitrile compound, carboxymethyl cellulose, hydroxyalkyl cellulose, polyvinyl alcohol, polyvinyl butyral, polyvinyl pyrrolidone, polyether, or a mixture of two or more thereof.
