PROBLEM TO BE SOLVED: To provide an indicator for indicating the existence of current and voltage, capable of visually confirming the existence of a charging state. SOLUTION: In this indicator a resistance is connected to a terminal of a current transformer 2 inserted into a main electrode 1 and the terminal of the resistance is connected to a terminal of a printed board on which a flashing circuit of a light emitting lamp is printed, and each terminal 9, 9' of two small electrodes 8, 8' separated respectively from the main electrode 1 in the right- angled directions at different distances are connected to the terminal 7' of the printed board 6' on which the flashing circuit of the light emitting lamp 5' is printed.
