Patent ID: 7755898

Claim:
A semiconductor module comprising: a base plate; a plurality of substrates placed on one surface of the base plate, with each substrate of the plurality of substrates including a switching element, a diode element, and a connection terminal area; and a parallel flow forming device that forms parallel coolant flow paths that are provided so as to be in contact with the other surface of the base plate, wherein: the coolant flow paths are formed such that coolant flows in a coolant flow direction, the switching element and the diode element are disposed in series in the coolant flow direction in each of the substrates, the switching element and the connection terminal area are disposed at positions that differ in a perpendicular direction with respect to the coolant flow direction in each of the substrates, a pair of substrates of the plurality of substrates is disposed in series in the coolant flow direction, the switching element is arranged on a first side in the perpendicular direction for one substrate of the pair of substrates and on a second side in the perpendicular direction for the other substrate of the pair of substrates, and the connection terminal area is arranged on the second side in the perpendicular direction for the one substrate of the pair of substrates and on the first side in the perpendicular direction for the other substrate of the pair of substrates.
