PROBLEM TO BE SOLVED: To provide a contact connection structure capable of reducing contact resistance without increasing a size of a terminal and complicating the terminal as much as possible.SOLUTION: A contact connection structure includes first contact parts 2a, 3 including an indented part 4 projecting therefrom and having a tin plating layer 3b formed on an outer surface thereof, and a tab section 11 having a tin plating layer 11b formed on an outer surface thereof, the indented part 4 of the first contact parts 2a, 3 sliding along the contact surface of the tab section 11 during a terminal insertion step, and the indented part 4 being brought into contact with the tab section 11 at a terminal-insertion completion position. On the contact surface of the tab section 11 on which the indented part 4 slides, there is provided an impact load applying section 13 for landing the indented part 4 on the contact surface of the tab section 11 at a position proceeding the terminal-insertion completion position in the indented part 4. |
