PROBLEM TO BE SOLVED: To provide a laminated battery capable of suppressing effectively a variation in resistance values caused between laminated bodies superposed in multi-stages. SOLUTION: In the laminated battery with a plurality of cathode plates and anode plates alternately laminated with a separator interposed, laminated bodies 10A, 10B are composed of and jointed by a plurality of positive and negative lead tabs 51A, 51B 52A, 52B extending from each of positive and negative electrode plates laminated on each of positive and negative current collector terminals 55A, 55B, 56A, 56B, and the two of the laminated bodies 10A, 10B are superimposed. The positive and negative current collector terminals 55A, 55B, 56A, 56B of each of the laminated bodies 10a, 10B are connected in parallel to the electrode tabs (positive and negative electrode tabs) 53, 54 of the same external connection terminals to form a current collecting passages branched into two of up and down directions between the electrode tabs 53, 54 and each of the laminated bodies 10A, 10B, and the up and down current collector passages are connected respectively by positive and negative electrode bus bars 57, 58.
