PROBLEM TO BE SOLVED: To provide measuring device for power source inspection capable of shortening the inspection time and preventing a short-circuit accident. SOLUTION: This measuring device 30 for power source inspection is equipped with a connection cable 20 for connection to a plug socket circuit, a change-over switch 5 for switching the ON/OFF state of electric connection between the plug socket circuit and the measuring device 30 for power source inspection, voltmeters 6, 7, 8, 9 for measuring and displaying the voltage of the plug socket circuit connected by the change-over switch 5, and a phase rotation detector 10 for detecting and displaying phase rotation (positive phase/ negative phase) of the plug socket circuit connected by the change-over switch 5. Hereby, the voltages and phase rotations of at least one or more alternating- current plug socket circuits can be inspected simultaneously collectively.
