A wire with terminal includes a wire in which a core is covered with a coating, and a terminalincluding a wire barrelto be crimped to the core exposed from the coating of the wire and an insulation barrelto be crimped to the coating of the wire. The wire is pulled rearwardly from the terminal. RecessesB are provided on a surface of the insulation barrelto be crimped and openings of the recessesB are shaped to become narrower toward a rear side. As the wire is pulled more rearwardly, the coating penetrating into the recessesB moves rearwardly of the recessesB to be compressed and hardened and becomes less likely to come out of the recessesB. Thus, impact strength can be enhanced.
