  "textContent": "A nonaqueous electrolyte secondary battery includes a positive electrode including a positive electrode collector, a positive electrode active material layer on part of the surface of the positive electrode collector, and an insulating layer on another part of the surface of the positive electrode collector; a negative electrode including a negative electrode collector; and a negative electrode active material layer on part of the surface of the negative electrode collector; a separator that insulates the positive and negative electrodes; and a nonaqueous electrolyte. A width of the negative electrode active material layer is wider than the positive electrode active material layer. The insulating layer protrudes from the negative electrode active material layer; and exhibits a thermal shrinkage factor of 13% or less in a direction parallel to the surface of a square insulating layer sample having a side length of 5 cm and heated at 150° C. for 1 hour.",
