WIRE HARNESS

It is an object of the present invention to realize a lighter and more space-saving wire harness having a function of retaining the shape of part of electric wires and an electromagnetic shield function. The wire harness includes a plurality of spliced and sheathed electric wires and a conductive shielding member. Each of the spliced and sheathed electric wires has a spliced core wire and an insulating sheath that covers the spliced core wire. The spliced core wire includes a first core wire that is a single conductive wire, and a second core wire that is a bundle of a plurality of conductive wires that are thinner and shorter than the first core wire, the second core wire being connected to an end portion of the first core wire. The shielding member is formed in a flexible tubular shape, and collectively covers the plurality of spliced and sheathed electric wires.
