摘要： An object is to provide a lithium ion secondary battery which maintains the electrical connections between each active material layer and a separator without using a firm housing, can have an increased energy density, can take an arbitrary shape, such as a thin shape, exhibits excellent charge and discharge characteristics, and has a large battery capacity. Positive and negative electrode active material particles are bonded to their respective current collectors to form a positive electrode and a negative electrode. The positive and the negative electrode active material layers are joined to a separator with a binder resin so that the joint strength between the separator and the positive and the negative electrode active material layers may be equal to or greater than the joint strength between the positive and the negative electrode active material layers and the respective current collectors to prepare a tabular laminated battery body having a plurality of electrode laminates. An electrolytic solution containing lithium ions is held in the voids possessed by the positive and the negative electrode active material layers and the separator to make an electrical connection between electrodes.
