PROBLEM TO BE SOLVED: To provide a bearing of motor and a method of manufacturing the same for attaining higher accuracy with a simplified method. SOLUTION: In a bearing 30 of motor for supporting the end of rotor shaft with the circular recesses 33, 34 formed at the end face of a columnar body 35 engaged with a hole provided at the axial center of a frame, there is provided a structure that a collar 36 is projected in the normal direction from the side surface of cylinder in the end face side of the columnar body 35 forming the circular recesses 33, 34 and divided into a plurality of portions in the circumferential direction. When the columnar body 35 is engaged with a hole of the frame, the collar 36 is set in contact therewith for the positioning in the axial direction. The circular recesses 33, 34 supporting the end part of the rotor shaft and the side surface of cylinder of the columnar body 35 to be engaged with the hole of frame are formed integrally with only one molding die.
