Disclosed is an inverter housing which is installed in a vehicle, and more particularly, an inverter housing which is capable of having a high heat dissipation effect and realizing a compact size. To this end, the inverter housing according to the present invention includes a body having a plate shape; a plurality of capacitor insertion portions formed to be recessed in a first direction of the body, so that capacitors are inserted thereinto, and integrally arranged to be spaced from each other; a plurality of switching device installation portions configured as spaces in which switching devices are installed, and arranged between the capacitor insertion portions in a second direction of the body opposite to the first direction; and a plurality of heat dissipation fins installed in the first direction of the body to face the switching devices with the body interposed therebetween.
