    Abstract: An electrochemical cell includes an electrode body that has a plurality of electrodes stacked on each other in a direction of a battery axis O, and an exterior body that has a first laminate member and a second laminate member, and that internally accommodates the electrode body. The exterior body includes an accommodation portion that internally accommodates the electrode body, and a sealing portion in which the first laminate member and the second laminate member are joined to each other in a state where the first laminate member and the second laminate member overlap each other so as to seal an inside of the accommodation portion. The accommodation portion includes a top wall portion and a bottom wall portion which face each other with the electrode body interposed therebetween in the direction of the battery axis, and a cylindrical peripheral wall portion which surrounds the electrode body from an outer side in a radial direction. The sealing portion is formed into a cylindrical shape which is bent along the peripheral wall portion and surrounds the peripheral wall portion over an entire periphery from the outer side in the radial direction, and is in contact with the peripheral wall portion from the outer side in the radial direction.
