Abstract
A prismatic secondary battery includes an electrode body having a positive electrode plate and a negative electrode plate, a prismatic outer casing accommodating the electrode body, a sealing plate sealing the opening of the prismatic outer casing, a negative electrode terminal attached to the sealing plate, and a negative electrode collector electrically connecting the negative electrode plate and the negative electrode terminal. An insulating member is disposed between the sealing plate and the negative electrode terminal. An insulating sheet is disposed between the sealing plate and the negative electrode collector. The insulating member and the insulating sheet are disposed so as to overlap with each other in a direction perpendicular to the sealing plate.
