PURPOSE:To improve the miniaturization, weight lightening and energy density of a battery by constituting an electrode-unit-laminated body by laminating a plurality of electrode units and an isolator containing electrolyte in order, and integrally joining the respective synthetic resin bodies of an electrode unit and a single-pole electrode unit at the respective circumferential portions. CONSTITUTION:An electrode-unit-laminated body where a positive electrode 3 is junctioned on one face of a film-like or sheet-like synthetic resin body 1 and a negative electrode 4 is junctioned on the other face thereof is made up by laminating a plurality of electrode units 6 made such that the positive electrode 3 and the negative electrode 4 are connected with a connection conductor 5 passing through the synthetic resin body 1 and an isolator 7 containing electrolyte in order. Further more, single electrode units 9 are abutedly arranged such that the positive electrode 3 or the negative electrode 4 is joined to both sides in the laminating direction of the electrode-unit- laminated body and one side of a film-like or a sheet-like synthetic resin body 1'. Then, the respective synthetic resin bodies 1, 1' of the electrode units 6 and the single electrode units 9 are integrally joined at the circumferential portions 1A, respectively. It is thereby possible to improve miniaturization, weight lightening and energy density of the battery. |
