PROBLEM TO BE SOLVED: To provide a power supply device which has a noise shield wall and enables downsizing.SOLUTION: A power supply device 1 includes: multiple electronic components 2; a base plate 3 on which the multiple electronic components 2 are placed; and holders 4. The holders 4 hold some of the electronic components 2 pressing the electronic components 2 to the base plate 3. The electronic components 2 form a main circuit part 10 and a noise filter 11 electrically connected with the main circuit part 10. The base plate 3 has a noise shield wall 5. The noise shield wall 5 is erected between the main circuit part 10 and the noise filter 11. The noise shield wall 5 shields radiation noise radiated from the main circuit part 10. Holder fixing parts 51 for fixing the holders 4 are formed at the noise shield wall 5. |
