NOVELTY - The collector (11) has a multi-layered structure comprising an insulation layer (13) sandwiched by electrically conductive layers (14), where the insulation layer is formed from a mixture of resin and adhesive. The adhesive included in the insulation layer is more than 0 wt percent and less than 3 wt percent relative to the insulation layer. The adhesive includes a tackifier made of rosin. The electrically conductive layers are in direct contact with the insulation layer and composed of metal foil, where the melting point of the insulation layer is 120 degree Celsius.    USE - Positive electrode current collector for use in a nonaqueous secondary cell (claimed) i.e. lithium ion secondary cell, utilized in a portable appliance, a power storage application and onboard application in an electric automobile.    ADVANTAGE - The adhesive included in the insulation layer is in a range more than 0 wt percent and less than 3 wt percent to the insulation layer such that the adhesive in the insulation layer can be effectively suppressed from leaking into the electrolyte, thus making reliability of the cell that can be effectively improved by suppressing peeling of the electrically conductive layers. The resin layers of the positive electrode current collectors are made from thermoplastic resin, and the thermal shrinkage rate at 120 degree Celsius can be made 1.5 percent or more in any planar direction such that electrodes can be made to be readily broken when abnormal overheating occurs in an overcharged state, thus preventing ignition effectively, and hence improving safety of the lithium ion secondary cell in an effective manner. The collector with thickness of the resin layer is 10 micrometer or more and 50 micrometer or less to achieve a balance between improving energy density and maintaining strength in the secondary cell. The positive electrodes can be formed by mixing the positive electrode active material, the electrical conductor, the thickener and the binder, adding a suitable solvent to create a pasty positive electrode mixture, coating the surface of the positive electrode current collector with the positive electrode mixture, drying the coating and compressing the result to increase the electrode density.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a nonaqueous secondary cell.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of a positive electrode current collector of a lithium ion secondary cell.
