<P>PROBLEM TO BE SOLVED: To provide an aluminum-based terminal fitting excellent in adhesion of a Sn layer provided on a surface thereof, and a terminal connection structure of an electric wire equipped with the terminal fitting. <P>SOLUTION: The aluminum-based terminal fitting includes a base material 10 made of an aluminum alloy, and is provided with an anodic oxidizing layer 20 formed on the base material 10 in a contact region of an electrical connection part electrically connected with another connecting object, and a Sn layer 30 formed so as to contact with the anodic oxidizing layer 20, and composing the uppermost surface of the contact region, and an electrically conductive part 31 composed of Sn. The electrically conductive part 31 is connected to the base material 10 from the Sn layer 30 through the anodic oxidizing layer 20. Since the adhesion between the base material 10 and the anodic oxidizing layer 20, and between the anodic oxidizing layer 20 and the Sn layer 30 are respectively excellent, the Sn layer 30 does not peel off easily from the base material 10. The terminal fitting can perform an electrical connection by the electrically conductive part 31 provided therein even if the anodic oxidizing layer 20 consisting of an insulator is provided on a surface of the base material 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
