  "textContent": "A nonaqueous electrolyte secondary battery includes: a positive electrode 4 including a positive electrode current collector and a positive electrode material mixture layer containing a positive electrode active material and a binder and provided on the positive electrode current collector; a negative electrode 5; a porous insulating layer 6 interposed between the positive electrode 4 and the negative electrode 5; and a nonaqueous electrolyte. The positive electrode 4 has a tensile extension percentage of 3.0% or more. The binder is made of polyvinylidene fluoride. The positive electrode current collector has a softening temperature lower than a crystalline melting point of the binder.",
