Patent ID: 7173188

Claim:
A straight angle conductor for a lead wire, comprising: a cladding material comprising a core-sheet metal and a conductor-sheet metal that sandwiches both surfaces of the core-sheet metal, wherein the conductor-sheet metal wraps both side end faces of the core-sheet metal to prevent the core-sheet metal from being exposed to an outside of the conductor-sheet metal, wherein the conductor-sheet metal has a crystal orientation with the following feature: IR=I (111)/{ I (200)+ I (111)}â‰§0.15, where I (111) represents X ray diffraction intensity of Surface (111), and I (200) represents X ray diffraction intensity of Surface (200), and wherein the conductor-sheet metal is formed of Cu, Au, or Ag, or an alloy material comprising Cu or Au, and wherein the core-sheet metal has a Vickers hardness equal to or less than 150 Hv and the conductor-sheet metal has a Vickers hardness equal to or less than 100 Hv.
