Elevator apparatus and deterioration judgment method of power storage element in the same

The invention can correctly judge the deterioration state of a power storage element when the power storage element is arranged in a car of the elevator apparatus. When a power receiving coil (13) isarranged in the car, and a power transmission coil (11) is arranged at a specific stop floor of a hoistway, and when the car stops at the specific floor and the power transmission coil (11) and the power receiving coil (13) are opposed to each other, power is supplied to the power receiving coil (13) in a non-contact manner, and the power storage element (14) is charged by means of the supplied power. Besides, the elevator apparatus includes a voltage detection unit that detects a measurement start voltage and a change event extracting unit for extracting an event which changes based on characteristics of the power storage element when each voltage is detected, and then the deterioration state of the electric storage element (14) is estimated by comparing the event extracted by the changeevent extraction unit with
