PROBLEM TO BE SOLVED: To provide a power supply device capable of enhancing heat dissipation of a heating component, while reducing noise.SOLUTION: A power supply device includes a substrate mounting one or a plurality of heating components such as a FET, a diode, a transformer and a coil, a fixing member for fixing the substrate, and a lid attached to the fixing member and covering the substrate. The lid can be attached to the fixing member. An electromagnetic shield is provided between the lid and heating component. The electromagnetic shield is configured to cover the periphery of a heating component, especially a component becoming a noise generation source, such as a switching element.SELECTED DRAWING: Figure 2 |
