PROBLEM TO BE SOLVED: To provide a cooling module that is increased in cooling effect by improving the heat radiating performance of heat radiating fins. SOLUTION: This cooling module is constituted by providing two heat pipes 15a and 15b which transfer the heat from heat generating parts to the heat radiating fins, and dividing the fins into two facing groups 13a and 13b of heat radiating fins on the main body 7 side of this module and those on a lid side. Then one 15a of the heat pipes 15a and 15b is thermally joined to the back of the fin in the group 13a on the main body 7 side, and the other heat pipe 15b is thermally joined to the back of fins in the other group 13b on the lid side. Consequently, heat is transferred through the groups 13a and 13b of fins from their backs to the front ends without lowering the temperature and the fins can effectively radiated heat as a whole when the module is operated for forcible cooling by a fan. In addition, the size of this module can be reduced without increasing the thicknesses of the divided two fin sections.
