PROBLEM TO BE SOLVED: To provide a core for a rotary machine wherein magnetic saturation in teeth can be more suppressed as compared with conventional cases. SOLUTION: The teeth 12 provided on the stator core 10 are respectively provided with leg portions 13 and wide end portions 14 that are formed between the leg portions 13 and the ends of the teeth and wider than the leg portions 13. The stator core 10 is formed by laminating multiple steel plates 30. The multiple steel plates 30 can be kept in laminated state by pushing the locking projections 20 formed on steel plates 30 into locking recesses 22 in other steel plates 30, positioned on the opposte side to the locking projections 20. The locking projections 20 are disposed only on the wide end portions 14 of the teeth 12 which are relatively wide. Therefore, magnetic saturation in the teeth 12 can be more suppressed as compared with conventional cases where the locking projections 20 are disposed at the leg portions 13 of the teeth 12 or on the boundary line L10 between the leg portions 13 and the wide end portions 14.
