[Object] A cooling device for a thin electronic equipment having a larger heat radiation area and preventing leakage of refrigerant. [Means for Solving Problems] A cooling device includes first and second cooling panels ( 1, 2 ) wherein a passage ( 11, 21 ) is formed by bonding together a top heat radiation panel and a bottom heat radiation panel each having a groove therein, and a circulation pump ( 3 ) for circulating refrigerant within the passage ( 11, 21 ). In the top heat radiation panel of the second cooling panel ( 2 ) are formed an outlet port through which the refrigerant flows out from the passage ( 21 ) to the circulation pump ( 3 ) and an inlet port through which the refrigerant flows in from the circulation pump ( 3 ) to the passage ( 21 ). The circulation pump ( 3 ) is fixed onto the top heat radiation plate of the cooling panel ( 2 ) so that the suction port and discharge port are aligned with the outlet port and inlet port, respectively.
