    摘要： 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 wires 1a made 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.

    摘要： The present disclosure provides a flat ribbon type conductive wire body and a flat ribbon type wire harness. The flat ribbon type conductive wire body includes a conductive core body, an insulating layer, and a shielding layer. The insulating layer wraps the conductive core body, and the shielding layer is disposed outside the insulating layer. The flat ribbon type conductive wire body has a good electromagnetic shielding function, a strong anti-electromagnetic interference capability and low requirements for installation space, can be widely used in occasions having high requirements for signal transmission stability, and improves the space requirement of the whole vehicle for wire harness layout.

    摘要： An aluminum alloy conductive wire that includes 0.15 mass % or more and 0.25 mass % or less of Si; 0.6 mass % or more and 0.9 mass % or less of Fe; 0.05 mass % or more and 0.15 mass % or less of Cu; 0.2 mass % or more and 2.7 mass % or less of Mg, and 0.03 mass % or less in total of Ti, V, and B. The aluminum alloy conductive wire has tensile strength of equal to or less than T1 MPa represented by T1=59.5 ln(x)+231 and conductivity of equal to or more than C % IACS represented by C=1.26x2−11.6x+63.4 in a case where a content rate of Mg in the aluminum alloy conductive wire is x mass %.
