A movable iron-core for an electromagnetic actuator integrally formed by fitting one end of a shaft member having an inner hole and formed of a soft magnetic material. The shaft member is formed of aferromagnetic steel material, the outer peripheral member is formed of a sintered member, and the shaft member and the outer peripheral member are formed integrally with each other by sintering bonding. Thus, excellent magnetic characteristics can be provided for the overall movable iron-core, excellent magnetic attraction force, wear resistance, and fatigue strength can be realized for the movable iron-core, and an electromagnetic actuator with high responsiveness which is requested in recent years can be manufactured.
