<P>PROBLEM TO BE SOLVED: To construct divided stator cores to be used for an inner rotor type motor into an annular stator core by a simple method using, for example, a heat shrinkage action, without using a method or a material, such as welding or adhesive which has an adverse impact on environment. Ž<P>SOLUTION: A plurality of divided iron cores 1, each consisting of a tooth 2 and a yoke 3 integrally formed, are arranged in an annular shape to construct a stator iron core 6. Thereafter, the outer periphery of the stator iron core 6 is covered with a plastic-deformed or elastic-deformed material and then a force is applied radially or axially, thus constructing the stator iron core easily.
