Abstract
A rotor is a magnet-embedded rotor incorporated in a traveling motor of a vehicle, and includes: a laminated core having steel sheets laminated to each other and a bonding layer for bonding the steel sheets adjacent to each other in a laminating direction; and a magnet embedded in the laminated core. When the rotor rotates at 11000 rpm, a maximum amount of displacement of an outer edge of the laminated core of the rotor in a radial direction is 0.1 mm or less.
