PROBLEM TO BE SOLVED: To provide a current auxiliary member capable of reducing electric resistance, flowing a large current by improving heat dissipation, and improving processability and solderability, and a printed circuit board having the same.SOLUTION: A current auxiliary member 1 has four or more of terminals 2, a conductive connection part 3, and heat dissipation parts 4. Four or more of terminals 2 are used for connecting to a conductive part 11. The conductive connection part 3 is arranged so as to face to a surface of a printed circuit board 10, and electrically connects four or more of terminals 2 with each other. The heat dissipation parts 4 extend from the conductive connection part 3 to an opposite side of the printed circuit board. The heat dissipation part 4 is arranged along a side connecting two terminals 2 of four or more of terminal 2, and the heat dissipation part 4 at a side surface 4A of the dissipation part 4 of at least one of two terminals 2, has a notch 5 at a root part connected to the conductive connection part 3. |
