PROBLEM TO BE SOLVED: To improve a heat radiation effect of a radiator for cooling a semiconductor device.SOLUTION: A heat conductive plate part 152 of a radiator 150 effectively radiates heat because it is wide in a contact area contacting with air, that is, a heat radiation area. In addition, since a coupling part 164 is formed in a bellows-like shape to make a plate-like part 166 function as a cooling fin, the coupling part 164 is wide in the contact area contacting with air, that is, the heat radiation area, and thus, effectively radiates heat. |
