Abstract
A wire conductor is made of aluminum or an aluminum alloy, and is not likely to, when it is ultrasonically welded to a connection terminal, cause a welding defect in a welded portion. A wire conductor includes: a lower strand layer in which a plurality of strands formed by twisting together a plurality of bare wiresmade of aluminum or an aluminum alloy are bundled and twisted together; and an upper strand layer formed by twisting a plurality of strands around an outer circumference of the lower strand layer, wherein in a cross section of the wire conductor that is orthogonal to its axial direction, a proportion of an area occupied by gaps formed between the lower strand layer and the upper strand layer to an area of gaps that are not occupied by the bare wires is 63% or less.
