The branch wall includes two plate-shaped portions that are continuous with each other at sides thereof on the upstream side in the air blowing direction of the fan and are inclined relative to the air blowing direction such that the two plate-shaped portions are separated from each other. A plurality of ribs that protrude from a surface of the branch wall facing the heat sink, each has a mountain-shaped plate shape with a most protruding top portion having an acute angle, each has a thickness equal to or less than an interval between fins of the heat sink, and the ribs are provided side by side in a thickness direction of the rib at an interval at which the rib is inserted between the fins.
