NOVELTY - The electrode comprises: a current collector having a pair of principal surfaces facing each other; and an active material layer that contains an active material, a binder and a conductive material and is placed on one of the principal surfaces of the current collector. The sum of the volume of the active material per unit area of the current collector and the volume of the conductive material per unit area of the current collector is 9.70x 10-3 cm3/cm2 to 24.6x 10-3 cm3/cm2. The volume of the active material is calculated from the average particle size D50 of the active material.    USE - The electrode is useful as: a positive electrode in non-aqueous electrolyte secondary battery (all claimed) such as lithium secondary battery for compact portable electronic devices, vehicle-mounted devices and high-capacity devices used for photovoltaic systems or power storage including nighttime power storage; and a negative electrode.    ADVANTAGE - The electrode exhibits an excellent rate characteristic even though the thickness of a coating is large, and is inexpensive.    DETAILED DESCRIPTION - The electrode comprises: a current collector having a pair of principal surfaces facing each other; and an active material layer that contains an active material, a binder and a conductive material and is placed on one of the principal surfaces of the current collector. The sum of the volume of the active material per unit area of the current collector and the volume of the conductive material per unit area of the current collector is 9.70x 10-3 cm3/cm2 to 24.6x 10-3 cm3/cm2. The volume of the active material is calculated from the average particle size D50 of the active material. The volume of the conductive material is calculated from the average particle size D50 of the conductive material. The pore volume of the active material layer per unit area of the current collector is 6x 10-3 cm3/cm2 to 20x 10-3 cm3/cm2. The active material layer is placed on both of the principal surfaces of the current collector, where the weight of the active material layers per unit area of the current collector is 30-76 mg/cm2.
