PROBLEM TO BE SOLVED: To provide a rotor core that prevents the bending or damage of a rotating shaft, in the rotor core into which the rotating shaft of a motor that is used for information apparatus and the like is press fitted. SOLUTION: A press-fitting portion 36 and clearances 35 are provided in the through hole 34 of a core sheet 12a. The rotating shaft 11 is press fitted into the core 12 formed by stacking the core sheets 12a. A resin film 37a that joins the rotating shaft 11 with the core 12 is formed in the clearances 35 so that the rotor core can be formed that suppresses the bending and damage of the rotating shaft 11, resulting in making it possible to provide a small, less noise, and highly reliable motor.
