CURRENT AUXILIARY MEMBER AND LARGE CURRENT SUBSTRATE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a current auxiliary member which achieves high radiation performance and enables a large current to flow therethrough.SOLUTION: A current auxiliary member 10 is electrically connected with a wiring pattern of a printed board by soldering and contains a conductive material. The current auxiliary member 10 includes: a plate like trunk part 1 disposed along a first surface arranged perpendicular to a main surface of the printed board; a first lead part 2a extending forward from a first side end of the trunk part 1; and a second lead part 2b extending rearward from a second side edge of the trunk part.
