    摘要： A non-aqueous electrolyte solution is provided that realizes a large capacity, exhibits high storage characteristics and cycle characteristics, and is capable of inhibiting gas generation.The non-aqueous electrolyte solution comprises a lithium salt and a non-aqueous solvent, and further comprises: a cyclic carbonate compound having an unsaturated bond in a concentration of 0.01 weight % or higher and 8 weight % or lower; and a compound expressed by general formula (Ia) in a concentration of 0.01 weight % or higher and 5 weight % or lower. (in the formula (Ia), R11 and R12 represent, independently of each other, an organic group that is composed of one or more carbon atoms and hydrogen atoms and may optionally contain one or more oxygen atoms but excludes unsaturated bonds, provided that at least either R11 or R12 has an ether linkage. The total number of carbon atoms of R11 and R12 is between 3 and 18, and the total number of oxygen atoms contained in R11 and R12 is between 1 and 6.)
