A lithium ion secondary cell comprises a plurality of single cells composed of a collector comprising positive electrodes composed of a metallic material coated with a positive electrode active substance; negative electrodes composed of a metallic material coated with a negative electrode active substance; separators interposed between the positive and negative electrodes; lugs of the metallic materials where the active substance is not coated; and conductors adapted to bunch and clamp the lugs of the positive and negative electrodes separately, the positive and negative electrodes being assembled in laminate alternatively, and the ends of the lugs of the positive and negative electrodes being welded to the respective conductors separately so that electric current can be taken out through the conductors.
