Abstract: During edgewise bending that is carried out on an aluminum alloy bus bar made of an aluminum alloy rectangular wire, an edgewise bending portion is heated to a temperature between 100 and 250° C. inclusive, and within 5 minutes after the heating, edgewise bending is carried out. In the aluminum alloy bus bar, the ratio A/B of Vickers hardness A in a heated portion to Vickers hardness B in a non-heated portion is at least 0.8. If necessary, flatwise bending is further carried out on the aluminum alloy bus bar, forming the bus bar into a predetermined shape.
