  "textContent": "A secondary battery suppresses generation of wrinkle at the outer peripheral edge portion of a negative electrode plate due to expansion of a negative electrode active material layer with use. The secondary battery includes a positive electrode plate with a positive electrode active material layer disposed on a first current collector, and a negative electrode plate with a negative electrode active material layer having an area larger than an area of the positive electrode active material layer disposed on a second current collector. The negative electrode plate includes a facing portion facing the positive electrode active material layer and a non-facing portion. The negative electrode plate and a separator are bonded through a bonding layer. The bonding strength of a second bonding portion that bonds the non-facing portion to the separator is larger than the bonding strength of a first bonding portion that bonds the facing portion to the separator.",
