PROBLEM TO BE SOLVED: To improve the cooling performance of a cooler.SOLUTION: A refrigerant flows in a refrigerant passage (101). A cooling part (102) is interposed in the refrigerant passage (101), and is in thermal contact with heat-generating components (200). The refrigerant passage (101) is provided in such a manner that an upstream side passage part (111) into which the refrigerant flows is arranged vertically below a downstream side passage part (112) from which the refrigerant flows. |
