1. An aluminum wire comprising a composition containing 3.00% by mass or less of Fe and 0.20% by mass or less of Si, and further containing 0.010% by mass or more and 0.500% by mass or less in total of at least one element selected from the group consisting of Cu, Mn, Mg, Zn, Ti, B, V and Ni, wherein a remainder consists of Al and inevitable impurities,
wherein, within an area of 25 μm×60 μm in a cross section perpendicular to a longitudinal direction of the aluminum wire, a length adding together all portions having crystal misorientation of more than 1 degree and 15 degrees or less between adjacent crystal grains is 0.6 mm or more and 4.8 mm or less, and
wherein electrical conductivity of the aluminum wire is 55% IACS or more.
