The purpose of the present invention is to construct a stator core which facilitates the winding of a coil without decreasing the accuracy of the tip position of teeth and without increasing the number of components. The stator core is provided with: a first stator portion which comprises a laminate of first stator pieces including first engaging teeth that can be attached to and detached from anannular first yoke portion, and first fixed teeth integrally formed with the first yoke portion; and a second stator portion comprising a laminate of second stator pieces including second fixed teethintegrally formed with a second yoke portion, and second engaging teeth that can be attached to and detached from the second yoke portion. These are stacked together such that the first engaging teethand/or the second fixed teeth, and the first fixed teeth and/or the second engaging teeth are provided with a coil portion. 构成不使齿部的末端位置的精度降低且不导致部件数量的增大而且还容易进行线圈的卷绕的定子铁芯。具备层叠第1定子件而成的第1定子部，上述第1定子件具有与环状的第1轭铁部卡合脱离自如的第1卡合齿部和与第1轭铁部一
