Abstract:
1. A semiconductor module comprising: a mount board including a laminated wiring section that includes a plurality of wiring layers formed on a surface of a substrate in a laminated manner, the plurality of wiring layers including an uppermost wiring layer and a plurality of inner wiring layers, each inner wiring layer being any one of the plurality of wiring layers excluding the uppermost wiring layer, and the plurality of inner wiring layers comprising at least a first inner wiring layer and a second inner wiring layer that is distinct from the first inner wiring layer; a first semiconductor device, a second semiconductor device, and a third semiconductor device that are each mounted on the mount board and electrically connected to the uppermost wiring layer; and a plurality of cooling structures that are each mounted on the mount board, wherein, edge portions of the second inner wiring layer, with one edge portion being on a side of the second semiconductor device and one edge portion being on a side of the third semiconductor device, are each exposed to the outside, and respective cooling structures are thermally connected to the edge portions of the second inner wiring layer.
