A multi-car elevator composed of two or more shafts (2L, 2R) and having a plurality of cages (3a, 3c) moving in the same shaft vertically is provided. The multi-car elevator includes: a failure detecting unit (6) that detects failure in the cages (3a, 3b, 3c) and a position in which failure is caused; an operating mode switching unit (7) for switchover to degrade operation for service of those cages (3a, 3b, 3c) in which failure is not detected, in the case where failure is detected; and a cage stop floor assigning unit (11) that assigns a stop floor to each cage (3a, 3b, 3c) between a highest floor or a lowest floor and that position in which the failure is caused. In the case where switchover to the degraded operation is made and a hall call is generated, a cage is assigned to service, the cage having been assigned as the stop floor to a floor called by the hall call.
