An method for manufacturing a sensor wheel for an automatic transmission and a sensor wheel are provided to precisely perform engine control by enabling an accurate speed measurement. A method for manufacturing a sensor wheel for an automatic transmission includes the steps of: preparing a circular disc; forming a first bending portion(35) by pressing the circumferential portion of the disc so that the circumferential portion has an annular shape; forming a tooth portion by performing blanking along the circumferential portion; forming a second bending portion by bending the tooth portion; and planarizing the outermost circumferential surface of the tooth portion and the second bending portion. |
