  "textContent": "A rectangular battery includes an electrode body that includes a plurality of stacked positive electrode plates, a rectangular outer casing that has an opening and that accommodates the electrode body, a cover plate that seals the opening and that is provided with an external terminal on a side opposite to a side of the electrode body, and a positive electrode collector terminal that is electrically connected to the positive-electrode-side external terminal and that is disposed inside the rectangular outer casing. Each positive electrode plate includes a positive electrode active material arrangement portion and a positive electrode collector tab, the positive electrode active material arrangement portion including a plate-like core body and a positive electrode active material containing layer that is provided at the core body, the collector tab being integrated with the core body and protruding from the positive electrode active material arrangement portion. Each positive electrode collector tab includes a curved portion that is positioned between the corresponding positive electrode active material arrangement portion and the positive electrode collector terminal in a Z direction (a region in the Z direction indicated by B), and has at least a part thereof curved.",
