PROBLEM TO BE SOLVED: To provide a contact connection structure capable of reducing contact resistance without upsizing a terminal and complexing the terminal as much as possible.SOLUTION: A contact connection structure comprises first contact parts 2a and 3 in which an indent part 4 is installed in a protruding manner and a second contact part 11. In a terminal insertion process, the second contact parts 11 of the first contact parts 2a and 3 slide on a contact surface of the second contact part 11. In a terminal insertion completion position, an outer peripheral surface of the indent part 4 comes into contact with the second contact part 11. A tin plating layers 11b and 11c are formed on an external surface of the second contact part 11. A thing plating 11c having higher height than other locations is formed in the region corresponding to the terminal insertion completion position of the indent part 4. |
