PROBLEM TO BE SOLVED: To realize a printed circuit board mount type electric current aid member which flows a large current of several tens of ampere, is not easily inductively heated by leakage magnetic flux, and achieves excellent heat radiation performance.SOLUTION: An electrical current aid part according to this invention includes: a plate like body part which is formed by a conductive member mounted on a printed circuit board, extends in a longitudinal direction, and has a pair of side parts and a pair of end parts; multiple lead parts formed so as to extend from lower end parts of the pair of respective side parts toward the printed circuit board and be inserted into through holes of the printed circuit board; and multiple protruding parts formed so as to extend from spaces between the lead parts in the respective side parts of the body part toward the printed circuit board and contact with the printed circuit board. The body part has multiple heat radiation fins at the upper or lower side of the end parts. |
