PROBLEM TO BE SOLVED: To improve workability in bonding a magnetic member in the accommodation hole of a rotor core for a motor, while suppressing degradation in the reliability of the motor. SOLUTION: The heated foamed sheet 21 for bonding a motor magnetic member, which employs a resin composition wherein a foaming agent to generate gas when heated is contained, is used for bonding the rotor core 10 for a motor, wherein an accommodation hole 11 larger than the magnetic member in the cross-sectional area is formed so as to allow the magnetic member to be accommodated therein is formed and the magnetic member accommodated in the accommodation hole 11. The heated foamed sheet is formed into a sheet shape that is to be interposed in the gap 11a between the magnetic member and the accommodation hole, and the sheet is heated, while being interposed to be foamed and increased in thickness so that one surface side is bonded to the magnetic member outer surface, and the other surface side is also bonded to the inner wall surface of the accommodation hole.
