PROBLEM TO BE SOLVED: To combine the installation performance and the heat dissipating performance of a power source device. SOLUTION: A power source device 40 includes a circuit substrate 41 mounted with AC-DC conversion components, a porous conductive case, and a heat dissipating plate 45, to which heat is transferred from the conversion components. The plate 45 is coupled to the case so as to form a part thereof, thereby forming a component storage chamber A, and the plate 45 is directed upward of a front frame 3. The case is attached to the frame 3 and a rear plate 10. Heat produced from the conversion components is dissipated to the outside of the device 40 via the plate 45, while the heat is dissipated to the outside of the device 40 by an air stream flowing from the outside of the device 40 through the holes and the interior of the device 40.
