Claim Text:
1. A terminal comprising: a connector portion electrically connectable to an external terminal; a tubular crimp portion extending from the connector portion, the tubular crimp portion being integral with the connector portion or coupled to the connector portion distinct therefrom, the tubular crimp portion being adapted to be crimped onto an electric wire, the tubular crimp portion having a longitudinal direction and a circumferential direction; and a transition portion that couples the connector portion and the tubular crimp portion, wherein the tubular crimp portion comprises one of a metal base material and a metal member having the metal base material, the metal base material being composed of one of copper and a copper alloy, the tubular crimp portion is a tubular member having a closed transition portion and an electric wire insertion opening side, the electric wire insertion opening side being adapted to receive and encompass a conductor end portion of an electric wire, the electric wire insertion opening side having a first width and the transition portion having a second width, the second width being less than the first width, the tubular crimp portion has a belt-shaped weld portion formed along a direction that is substantially the same as the longitudinal direction of the tubular crimp portion, a RD-direction of the metal base material being substantially aligned with the circumferential direction of the tubular crimp portion, and a sum of area ratios R1, R2 and R3 is greater than or equal to 15%, where R1, R2 and R3 are area ratios of crystal grains in the metal base material oriented substantially in Cube orientation, RDW orientation, and Goss orientation, respectively, facing a (100) plane of a face centered cubic lattice with respect to the RD-direction.
