Abstract
A semiconductor module includes a cooling device that includes: a ceiling plate; a side wall; a bottom plate; a plurality of pin fins having a polygonal shape and arranged in a matrix form in which one end of the respective pin fins is connected to a fin region having a rectangular shape; an inlet for a coolant at a first position adjacent to a part of one of long sides of the fin region, and an outlet for the coolant at a second position adjacent to a part of the other long side of the fin region. The matrix directions of the respective pin fins make an angle with a straight line connecting the first position and the second position, and a length of a segment of the straight line passing across the fin region is longer than a length of short sides of the fin region.
