PROBLEM TO BE SOLVED: To provide a motor which can improve the selectivity of the magnetic property of a stacked core and can improve the rotational accuracy. SOLUTION: In the motor 1A where a coil 14 is wound on a stacked core 13, the stacked core 13 is made by stacking unit core parts 17, where a plurality of projections 18d made in one magnetic steel plate 18 between two kinds of magnetic steel plates 18 and 19 different in magnetic properties are press-fitted each in a plurality of holes 19d made in the other magnetic steel plate 19 thereby being integrated together, in the direction of the axis C1 of rotation of a shaft 10.
