In a high strength and high electrical conductive nano crystalline grain multi-layer copper alloy sheet, a plurality of high strength and high electrical conductive nano crystalline grain multi-layer manufactured by roll-bonding an oxygen free copper (OFC) alloy sheet and a deoxized low-phosphorous copper (DLP) alloy sheet are plastically bonded by roll-bonding method so that an OFC alloy layer and a DLP alloy layer are alternated to each other to have electrical conductivity of 85 IACS(%) or more and tensile strength of 500 MPa or more. |
