Abstract: An electric wire is an electric wire to be routed under the floor of a vehicle such as an electric vehicle. The electric wire includes: a conductive first conductor that is formed in a single bar shape; a conductive second conductor that is formed by bundling a plurality of element wires; and a fusion junction that is formed by melting and joining an end of the first conductor and an end of the second conductor in a abutting state therebetween in an axial direction.
