Abstract

A terminal includes a connector portion, a tubular crimp portion that crimps/joins with a wire, and a transition portion joining the two portions. The tubular crimp portion is composed of a metal member including a base material of copper or copper alloy with 0.20-1.40 mm thickness and a coating layer of tin, tin alloy, nickel, nickel alloy, silver or silver alloy with 0.2-3.0 μm thickness formed on the base material. The tubular crimp portion has a weld portion formed by butt-welding and having, in its cross-section perpendicular to a terminal longitudinal direction, a phase existing therein of tin, tin alloy, nickel, nickel alloy, silver or silver alloy greater than 0.01 μm. The tubular crimp portion is a closed tubular body with one end opposite to a wire-insertion-opening being closed.
