A fastening structure includes a fastening member including a bolt and a plurality of fastened members that are fastened and fixed to the fastening member. Further, the bolt contains pure aluminum or an aluminum alloy. At least one fastened member of the plurality of fastened members contains pure aluminum or an aluminum alloy. Pure aluminum or an aluminum alloy of a screw portion of the bolt is brought into direct contact with pure aluminum or an aluminum alloy of at least one fastened member.

An aluminum wirehas a composition containing at least one element of Fe: 0 to 2.0 mass %, Mg: 0 to 1.0 mass %, Zr: 0 to 0.5 mass %, Si: 0 to 1.2 mass %, or Ni: 0 to 0.3 mass %, with the remainder being composed of aluminum and unavoidable impurities. In a cross sectionperpendicular to the longitudinal directionof the aluminum wire, the surface area proportion of component crystals for which the anglebetween the longitudinal direction and the &#x3c;111&#x3e; direction of the crystal is 10&#xb0; or less, relative to the total surface area of the cross section, is 50% or greater, and the surface area proportion of component crystals for which the anglebetween the longitudinal direction and the &#x3c;111&#x3e; direction of the crystal is 20&#xb0; or less, relative to the total surface area of the cross section, is 85% or greater.
