More Information
Summary:An electrical wire includes an aluminum element wire that has an aluminum base material and carbon nanotubes dispersed in the aluminum base material, in which the aluminum element wire has an electrical conductivity of 62% IACS or more and a tensile strength of 130 MPa or more. The aluminum base material is a polycrystalk having a plurality of aluminum crystal grains. Further, a carbon nanotube conductive path, which is composed of the carbon nanotube, and forms a conductive path allowing electricity to conduct therethrough in a longitudinal direction of the aluminum element wire by being present in a part of grain boundaries between the plurality of aluminum crystal grains in a transverse cross section of the aluminum base material, and being present along the longitudinal direction of the aluminum element wire, is formed in the aluminum base material.
