PROBLEM TO BE SOLVED: To provide a power supply device capable of inhibiting a transformer and a switching element from being affected by each other's heat generation and resulting in malfunctions.SOLUTION: A power source device 10 includes: a substrate 11; a transformer 12 mounted on a surface of the substrate 11; and an FET 13 which is electrically connected with the transformer 12 and is mounted on a rear surface of the substrate 11. The FET 13 is disposed at a position different from a position on the rear surface of the substrate 11 which corresponds to a position on the front surface where the transformer 12 is mounted. |
