Zusammenfassung:	Provided is a non-aqueous secondary battery having excellent high-temperature cycle characteristics and low-temperature output characteristics. The non-aqueous secondary battery includes a positive electrode, a negative electrode, a separator, and an electrolyte solution. At least one of the positive electrode, the negative electrode, and the separator includes a porous membrane. The porous membrane contains non-conductive particles and a polymer that has a nitrile group and includes an alkylene structural unit. The electrolyte solution contains a non-aqueous solvent and a supporting electrolyte. A propionic acid compound constitutes at least 50 volume% and not more than 100 volume% of the non-aqueous solvent.
