Stage: PROBLEM TO BE SOLVED: To provide an electrode for a non-aqueous electrolyte secondary battery, comprising a lower ground layer capable of sufficiently suppressing falling and peeling of an electrode mixture material layer while reducing a thickness as much as possible.SOLUTION: An electrode for a non-aqueous electrolyte secondary battery comprises: a collector; an electrode mixture material layer; and a conductive lower layer that is provided between the collector and the electrode mixture material layer. The lower layer at least contains: a styrene-acrylic acid ester copolymer; a carbon material; and a polyacrylic acid. A content of the styrene-acrylic acid ester copolymer in the lower layer is 45 mass% or more and 77.5 mass% or less. In the polyacrylic acid, a rate of a neutralization carboxyl group neutralized by an alkali metal ion of a carboxyl group provided in the polyacrylic acid is 25% or less, and a basis weight of the electrode mixture material layer per one surface of the collector is 15 mg/cm2 or more and 70 mg/cm2 or less.SELECTED DRAWING: None (Grant)
