PROBLEM TO BE SOLVED: To provide a core for a rotating machine which can reduce iron loss and cogging torque, can enhance the space factor of a coil, and can be manufactured easily, and also provide a rotary machine. SOLUTION: A stator core 6 is split into a plurality of numbers in the peripheral direction, while being mutually twisted at a specified skew angle, in the direction of the rotary axis line. More specifically, in split bodies 60, the center parts of slots which are adjacent to each other in the stator 5 are formed of the opposite end sides of the split bodies 60 and are split and formed, while being twisted at an angleθof, for example, 2 to 35 degrees with respect to the rotation axis line from the opposite end sides. The split bodies 60 are formed by respectively compressing metal powder coated with an insulating material. That is the surface of the metal power is subjected to insulation treatment, and then the metal powder is compressed with a molding die to be molded as a compound soft-magnetic substance.
