ABSTRACT:
A magnetism property of an armature is increased by including a moving core of sintered metal of 1LSS to 3LSS, and a shaft of a ferromagnetic material. By contrast, a stator core contains 0.005 to 0.1 weight % resin powder, whose particle diameter is set to 50 μm or less, in particular, 25 μm or less, so as to decrease a core loss and increase a magnetism property. The stator core thereby becomes approximately equivalent to the armature in a direct current magnetism property, so that an electromagnetic actuator and a fuel injection valve that are excel in suction force and response are provided.
