PROBLEM TO BE SOLVED: To provide a power supply device which upgrades the easiness of assembling and the resistivity against mechanical impact by improving an insulation plate and a shield plate, which are respectively mounted on the power supply circuit board which converts a commercial AC power supply to a DC power supply. SOLUTION: The power supply device has a power supply circuit board which converts a commercial AC power supply to a DC power supply. The power supply circuit board has the shield plate which is mounted on its back surface with a predetermined spacing and the insulation plate which electrically insulates between the power supply circuit board and the shield plate. The insulation plate is disposed with a plurality of ribs which keeps a space from the power supply circuit board, and each shield plate is disposed with hooks on the free end of the supporting part which is engaged with the power supply circuit board. |
