PROBLEM TO BE SOLVED: To provide a power supply device arranged to prevent electrolyte from adhering to a peripheral circuit even when an explosion-proof valve is activated in a simple manner at a small cost.SOLUTION: The power supply device includes: a circuit board E; an electrolytic capacitor 120 mounted onto the circuit board E; and a guide J disposed adjacent to the electrolytic capacitor 120. The electrolytic capacitor 120 has an explosion-proof valve 121 that opens for spouting inner electrolyte H to the outside in a predetermined case. The guide J is disposed facing the explosion-proof valve 121 being separated away therefrom at least a predetermined distance without being directly attached to the electrolytic capacitor 120 to prevent the spouted electrolyte H from adhering to the circuit board E.SELECTED DRAWING: Figure 2 |
