Abstract

Abstract There is disclosed a non-aqueous electrolyte secondary battery comprising a cathode can, a cathode pellet, a separator, an anode can, an anode pellet, and a non-aqueous electrolytic solution. At the portion in contact with the cathode can of the cathode pellet and the portion in contact with the anode can of the anode pellet, layers containing powder having conductive property are respectively formed. The powder having conductive property is aluminum powder on the cathode side and is copper powder on the anode side. The layers containing powder having conductive property are integrally molded as the result of the fact that they are compression-molded along with a cathode active material and an anode active material.
