Abstract
A compressor wheel that can more effectively and accurately detect its rotational unbalance than before is provided. The compressor wheel is disposed in a compressor assembly, the compressor wheel including a boss portion mounted on a rotation shaft, a rear plate portion disposed on an opposite side of a tip end portion disposed on one end side of the boss portion, the rear plate portion extending perpendicular to an axial direction of the rotation shaft, and a sensor detection surface formed on a circumferential surface of the tip end portion of the boss portion or on a circumferential surface of the rear plate portion, the sensor detection surface being inclined to the circumferential surface of the end portion or the circumferential surface of the rear plate portion, the sensor detection surface being detectable by an optical sensor that irradiates the sensor detection surface with light and detects light reflected therefrom.
