PROBLEM TO BE SOLVED: To improve junction strength of a tab, positive electrode and negative electrode of laminated cells. SOLUTION: The laminated cells are formed by forming an internal electrode pair 101 by laminating the positive electrode 101a and negative electrode 101b via a separator 101c, sealing the internal electrode pair 101 by an exterior package 10 while being dipped in an electrolyte, respectively joining each layer of the positive electrode 101a and negative electrode 101b to a positive electrode tab 21 and negative electrode tab 22, and protruding the positive electrode tab 21 and negative electrode tab 22 out from the exterior package 10. The positive electrode tab 21 is provided so as to cover the whole top face of the internal electrode pair 101, and the negative electrode tab 22 is provided so as to cover the whole bottom face of the internal electrode pair 101.
