Abstract: The present disclosure relates to an electric power module and an inverter apparatus having the same. The electric power module of the present disclosure may include a power device that converts the frequency of input power for output; a housing in which a passage of cooling fluid is disposed to accommodate the power device therein, and a cooling member, one side of which is in direct heat exchange with the power device, and the other side of which is in direct heat exchange with the cooling fluid, wherein the cooling member is made of a metal foam having a multi-porous structure. As a result, it may be possible to increase a heat transfer area of the heat conductor, and suppress the occurrence of pressure loss in the cooling fluid.
