  "textContent": "A method of producing an electrode assembly comprises: a stacking step to stack a positive electrode and a negative electrode with a separator interposed therebetween to form a stack; a winding step to wind the stack to form a wound body; and a pressing step to press the wound body to form a wound electrode assembly having a flat form. A press load in the pressing step is less than 140 kN. A thickness of the separator in the wound electrode assembly is from 16 μm to 20 μm. When the press load is denoted as A (kN), the thickness of the separator in the wound electrode assembly is denoted as B (μm), and a thickness of the negative electrode in the wound electrode assembly is denoted as C (μm), [A/(B/C)] is from 190 kN to 473 kN.",
