Abstract: Provided are an electric wire including: a core wire in which twisted wires having element wires are twisted in a same twisting direction as that in each of the twisted wires; and a connector. The connector includes: a terminal metal fitting having a terminal connection part fitted and connected to a mating terminal connection part in the fitting connection direction, and an electric wire connection part connected to a core wire exposed part; and a housing that draws out the electric wire from a storage chamber in the intersecting direction. The terminal of the electric wire includes a bent part in which a coated terminal part is bent with the core wire. The electric wire is formed such that a returning force becomes smaller than an absolute value of a spring force.
