PROBLEM TO BE SOLVED: To provide a contact connection structure capable of reducing contact resistance without increasing a terminal size or complicating as much as possible.SOLUTION: The contact connection structure includes: first contact parts 2a, 3 provided with three or more first indent parts 4 projected on a same circumference; and a second contact part 11 provided with one second indent part 12. In a terminal insertion process, the first indent parts 4 of the first contact parts 2a, 3 slide the second contact part 11. The second indent part 12 of the second contact part 11 slides the first contact part 3. At a terminal insertion completion position, the second indent part 12 enters into a position surrounded by the three or more first indent parts 4. Outer circumferential surfaces of the first indent parts 4 are respectively brought in contact with an outer surface of the second indent part 12. |
