PROBLEM TO BE SOLVED: To obtain a wiring board unit capable of inhibiting temperature rise in a printed wiring board which is caused by heat generated by a power module electrically connected with the printed wiring board and transmitted to the printed wiring board.SOLUTION: A wiring board unit includes: a wiring board 1 for mounting electronic components; a power module 2 having a terminal 2a; and a wiring auxiliary member 4 which determines relative positions of the terminal 2a and the wiring board 1. The wiring auxiliary member 4 includes multiple heat radiation parts 4a extending in a direction perpendicular to a direction that the wiring auxiliary member 4 extends. |
