摘要： An electrode for a non-aqueous electrolyte battery includes a current collector formed of aluminum foil or aluminum alloy foil, and an active material-containing layer formed on a surface of the current collector and containing an active material, a conductive agent and a binder. The conductive agent comprises a carbon particle group containing first carbon particles each exhibiting an aspect ratio of more than one. A portion of each of the first carbon particles is embedded into the current collector to the depth corresponding to 20 to 50% of the thickness of the current collector. A major axis of each of the first carbon particles has a length of 1.05 to 1.50 times as large as the thickness of the active material-containing layer.
