Abstract
A nonaqueous electrolyte secondary battery in accordance with the present invention is provided with an electrode bodyincluding a positive electrodeand a negative electrode, and a nonaqueous electrode. The electrode bodyis constituted by a plurality of different constituent members. At least two constituent members among the plurality of constituent members constituting the electrode bodyinclude respective particulate polymershaving a melting point within a temperature range from 80° C. to 120° C., with these two members being different from each other. The electrode bodyis provided with the positive electrodeincluding a positive electrode active material layeron a positive electrode collector, the negative electrodeincluding a negative electrode active material layeron a negative electrode collector, separatorsA,B interposed between the positive electrodeand the negative electrode, and nonaqueous electrolyte. It is preferred that two or all of the positive electrode, the negative electrode, and the separatorsA,B include the particulate polymers
