Disclosed is an elevator apparatus having a power outage operation function while including an emergency stop device actuated by an electric actuator. The elevator apparatus includes a car, an emergency stop device provided at the car, a drive mechanism configured to drive the emergency stop device, an electric actuator configured to actuate the drive mechanism, and a controller configured to control an operation of the car. The electric actuator includes a movable element mechanically connected to the drive mechanism, and an electromagnet facing the movable element. The elevator apparatus further includes a DC power supply connected to the electromagnet via a power supply contact and configured to excite the electromagnet, and a storage battery connected to the electromagnet. The controller cuts off the power supply contact during power outage, and the electromagnet is excited by the storage battery when the power supply contact is cut off.
