description A secondary battery is provided with: a plurality of positive electrodes each having a positive electrode core and a positive electrode active material disposed on the positive electrode core; a plurality of negative electrodes each having a negative electrode core and a negative electrode active material disposed on the negative electrode core; one or more diaphragms; and an adhesive that is applied to at least one side surface in the thickness direction of the separator so that the area density is substantially constant. The secondary battery includes a laminated portion in which a positive electrode and a negative electrode are alternately laminated with a separator interposed therebetween, and the area of an adhered portion of an adhesive on the outer side of the laminated portion in the lamination direction is larger than the area of an adhered portion of an adhesive on the inner side of the laminated portion in the lamination direction. 二次电池具备：多个正极，该正极具有正极芯体和配置在该正极芯体上的正极活性物质；多个负极，该负极具有负极芯体和配置在该负极芯体上的负极活
