PROBLEM TO BE SOLVED: To provide an aluminum base terminal fitting in which stress relaxation is difficult, and different metal contact corrosion (battery corrosion) can be reduced, and to provide a terminal connection structure of a wire.SOLUTION: A terminal fitting 10 includes a conductor connection to be connected with a conductor 210 composed of an Al alloy, or the like, and a fitting part 13 to be connected with a portion of the other terminal fitting (e.g., a male fitting part 140). The fitting part 13 includes a cylindrical box part 14 extending to the conductor connection, and a resilient piece 15 located on the inside of the box part 14 and is brought into contact with the male fitting part 140 by a biasing force. The resilient piece 15 is bonded to the box part 14. The conductor connection and the box part 14 are composed of an aluminum alloy. In a conduction path from the box part 14 to the male fitting part 140 via the resilient piece 15, a contact part of an Al-based member and a Ti-based member composed of titanium or a titanium alloy is provided. Since the contact current is small between Al-Ti, battery corrosion can be reduced. Since the resilient piece 15 has a high strength, stress relaxation is difficult. |
