PROBLEM TO BE SOLVED: To provide an electrochemical element comprising an electrode wherein the formation of a lead part is facilitated. SOLUTION: A plurality of sheet-like square current-collecting bodies 112, electrode layers 113 formed on each of a plurality of collectors 112, and electrolyte parts which provided adjoin the electrode layers 113 are provided, and the electrode layer 113 is formed on the collector 112, leaving a band-like part 114 along one side of the square of the collector 112, and the plurality of collectors 112 comprise a first group of collectors laminated with the side aligned in a first direction and a second group of collectors laminated with the side aligned in a second direction different from the first direction, while the first and second groups of collectors are laminated alternately with the electrolyte part in between. The band-like part may be used as a lead part of an electrochemical element, and that part is provided over the entire on side of a square of the collectors 112. |
