PROBLEM TO BE SOLVED: To provide a contact connection structure capable of reducing contact resistance without bringing about terminal upsizing and like.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. On the contact surface side of the second contact part 11, a recess 12 into which the outer peripheral surface of the indent part 4 enters in a state in which it is in contact with the periphery of the recess is provided in the terminal insertion completion position. |
