<p>PROBLEM TO BE SOLVED: To provide a power distribution board capable of securing the insulation between a heat dissipation member and a bus bar.SOLUTION: A switching board (power distribution board) 10 includes bus bars 30, 40, 50 and a heat dissipation unit 70 disposed to be overlapped with the bus bars 30, 40, 50. The heat dissipation unit 70 includes a heat dissipation plate 71 and a frame 72. The heat dissipation plate 71 is a member to be overlapped with the bus bars 30, 40, 50 through an adhesive layer 78, and has an opposite surface facing the bus bars 30, 40, 50 and four side faces perpendicular to the opposite surface. The frame 72 is a member having insulation properties and disposed to be in contact with the side faces of the heat dissipation plate 71.</p> |
