A sprocket for a chain drive using a roller or bushing chain has a plurality of different pitch angles, including both pitch angles larger than the standard pitch angle, and pitch angles smaller than the standard pitch angle. The number of pitch angles in the sprocket larger than the standard pitch angle is greater than the number of pitch angles in the sprocket smaller than the standard pitch angle. The sprocket teeth are integrally molded with the sprocket by sintering.
