PROBLEM TO BE SOLVED: To prevent displacement of insulating wedges inserted into slot openings for the enhancement of reliability and obtain a stator excellent in workability and advantageous in cost. SOLUTION: As insulating treatment for slots 22 in a stator core 14, wedge pieces 26 and 27 are inserted to close the openings 23 of the slots 22. In this configuration, a plurality of the wedge pieces 26 and 27 are coupled with one another at their bases 28. Thus, the wedge pieces are integrated to obtain a wedge configuration 25.
