PROBLEM TO BE SOLVED: To provide a power supply device that prevents a state where a voltage cannot be supplied to a supply target. ! SOLUTION: A power supply device 1 includes a first supply path having a first series regulator 21 for adjusting a voltage supplied from a battery 10 to supply the adjusted voltage to a first micro computer 31, and a second supply path having a second series regulator 22 for adjusting the voltage supplied from the battery 10 to supply the adjusted voltage to a second micro computer 32. The first supply path is connected to the second supply path via a third switch 43 on a downstream side of the first and second series regulators 21 and 22. The first micro computer 31, when a detected voltage of the first supply path is different from a voltage of the first supply path to be normally detected, switches the third switch 43 from OFF to ON. !
