Abstract: A method of producing a lithium ion secondary battery includes: a first winding process of winding a positive electrode plate (2) in a roll shape to form a first roll (11) and to provide a curling tendency to the positive electrode plate (2), and of winding a negative electrode plate (3) in a roll shape to form a second roll (12) and to provide a curling tendency to the negative electrode plate (3); and a second winding process of unrolling the positive electrode plate (2) from the first roll (11), unrolling the negative electrode plate (3) from the second roll (12), and winding the unrolled positive electrode plate (2) and negative electrode plate (3) in a roll shape to form a third roll (13) while allowing the positive electrode plate (2) and the negative electrode plate (3) to overlap with each other and maintaining the curling tendency.
