PROBLEM TO BE SOLVED: To provide a core that has a high flexibility in a shape and can be inexpensively manufactured, an armature core, and a motor. SOLUTION: In a stator core 10, both the ends in the axial direction are composed of a pair of core constructs 20, 20 made of powder, thus increasing the degree of freedom in the shape of both the ends of the stator core 10. Additionally, a core construct 21 made of a steel sheet by laminating the steel sheet is sandwiched between the pair of core constructs 20, 20 made of powder, thus reducing manufacturing costs as compared with a case when the entire stator core 10 is composed of composite materials.
