NOVELTY - The electrode (10) has active material layers (22, 32) formed on electrical power collectors (21, 31) such that exposed parts (21b, 31b), in which a part of the power collectors is exposed are remained. An insulation part (50) covers a boundary part (23) of the active material layers and the exposed parts, and is equipped with an adhesion area (50a) formed in a surface opposite to the power collectors, where the adhesion area consists of an adhesive material. A non-bonded area (50b) does not contain the adhesive material, and is located in a side of the active material layers.    USE - Electrode for a battery e.g. lithium ion secondary battery (all claimed) such as non-aqueous electrolyte lithium ion secondary battery, that is utilized for a driving power supply and an auxiliary power supply i.e. motor, of a vehicle e.g. electric vehicle (EV), fuel-cell vehicle and hybrid electric vehicle (HEV), in an automobile industry and an electronic device in front-end electronic industry.    ADVANTAGE - The non-bonded area does not contain the adhesive material, and is located in the side of the active material layers, so that elution of the adhesive material at time of electrical potential change of the active material layers and charging/discharging of the battery can be suppressed by the insulation part, fall of electrolytic ionic conductivity can be suppressed, and cycling characteristics of the battery can be improved.    DETAILED DESCRIPTION - The active material layers are rectangular-shaped active material layers. The adhesive material is a water-dispersion-type binder i.e. aqueous binder, and an organic solvent binder i.e. non-aqueous binder. An INDEPENDENT CLAIM is also included for a battery.
