Abstract: To provide an electromagnetic brake and an electric motor in which, in the case of using the motor with its shaft thereof in a vertical position, static friction torque and dynamic friction torque caused by electromagnetic brake portions is reduced, thereby enabling to provide reliable motor torque on the motor output shaft, and stable braking. The electromagnetic brake includes: a hub attached to a rotating shaft and rotated with rotation of the rotating shaft; a friction plate rotated in engagement with the hub and movable in an axial direction; brake plates sandwiching the friction plate, held against rotation by the rotating shaft, and movable in the axial direction; a brake plate retainer for fixing the brake plates in a direction of shaft rotation and retaining the brake plates in an axially movable manner; a pressure transmitter for receiving pressure and pressing the brake plates; a pressure generating mechanism for generating pressure to be applied to the pressure transmitter; and a stress generating mechanism for generating stress against the pressure applied to the pressure transmitter. Also, a stepped portion is provided on at least one of the brake plate retainer and the hub.
