。 A shutter curtain that moves up and down with the driving force of an electric motor is formed of a plurality of panel bodies connected at a predetermined interval in the vertical direction, and even after the shutter curtain has landed, it continues to lower and seal. In an electric shutter configured to fully close the shutter curtain, a drive control means is provided for inputting a detection signal from an obstacle detection means disposed at the lower end of the shutter curtain to emergency stop the drive of the electric motor. An operating position detecting means is provided which detects and releases the emergency stop control of the drive control means when the curtain reaches a position near the landing during the lowering operation, and further includes an operating position detecting means that detects and releases the emergency stop control of the drive control means when the curtain reaches a position near the landing during the lowering operation. A safety device for an electric shutter, characterized in that the drive control means is provided with abnormality determination means for determining that the obstacle detection means is abnormal if a detection signal is not input from the obstacle detection means.
