A connector-equipped electric-wire bundle including a plurality of types of electric wires different in conductor cross-sectional area and elongation. The connector-equipped electric-wire bundle comprises a first electric wire having a first conductor, and a second electric wire having a second conductor with a greater cross-sectional area and a greater breaking elongation than those of the first conductor. A second connector terminal having, as a second crimp portion, only a conductor barrel and a water-proofing-plug barrel is attached to an end of the second electric wire, and a first connector terminal having, as a first crimp potion, a conductor barrel, a water-proofing-plug barrel and an intermediate barrel is attached to an end of the first electric wire. The intermediate barrel is crimped onto an insulating cover in an intermediate region between the end of the conductor of the first electric wire and a water-proofing plug.
