Abstract: In a rotary electric machine having a rotor core of a skew structure, when one of the core blocks is sequentially stacked on the other of the core blocks to form a step skew, a communication reference groove is formed along an axial direction of the rotor core by aligning a side section of a short protruding section in one core block with a side section of the long protruding sections in the other core block, and by aligning a side section of a long protruding section in one core block with a side section of a short protruding section in the other core block. The core blocks are correctly stacked by aligning the side section of the long protruding sections with the side section of the short protruding sections.
