PROBLEM TO BE SOLVED: To provide a power supply device capable of improving manufacturing efficiency while securing sufficient visibility.SOLUTION: The power supply device comprises a circuit board 2a on which a circuit configuration component 31, a connecting connector 32, and a light-emitting component for operation confirmation are mounted, and a chassis 3 provided with an open part 3a for holding the circuit board 2a and causing the connecting connector 32 to be exposed. The light-emitting component is configured with a surface mount type LED 33, and is disposed on a connection face 22 which is the reverse side of a placement face 21 of the circuit board 2a on which the circuit configuration component 31 and the body part of the connecting connector 32 are placed. A through-hole 23 is formed in the vicinity of a position of the circuit board 2a at which the surface mount type LED 33 is disposed, so that light irradiation on the open part 3a of the chassis 3 is made allowable by letting a light L emitted from the surface mount type LED 33 pass from the connection face 22 to the placement face 21 through the through-hole 23. |
