PROBLEM TO BE SOLVED: To provide a core of an outer rotor type motor, a separate type core to be forced into and fixed, capable of reducing an assembly insertion pressure. SOLUTION: A single partial core 90 is configured by alternately stacking a first core blank plate 1 having a first projection portion 1a and a first recess portion 1b, and a second core blank plate 2 having a second projection portion 2a and a second recess portion 2b. The first projection portion 1a of the first core blank plate 1 cannot be inserted into the first recess portion 1b of the first core blank plate 1 of an adjacent partial core 90 from a stack horizontal direction, but inserted into the second recess portion 2b of the second core blank plate 2 from this direction. The second projection portion 1a of the second core blank plate 2 can be inserted into the first recess portion 1b of the first core blank plate 1 and the second recess portion 2b of the second core blank plate 2 from the above direction. The first projection portion 1a of the first iron core blank plate 1 is inserted into the second recess portion 2b of the second core blank plate 2 from the stack horizontal direction, and then, slides in a stack direction and forced into the first recess portion 1b of the first core blank plate 1.
