An electromagnetic actuator device reduces pulsation and improves thrust, and includes: a magnet; and an armature that moves relative to the magnet. The armature includes: a plurality of teeth formed in a relative movement direction; a plurality of slots between the plurality of teeth; a yoke connecting the plurality of teeth; and a winding around the plurality of slots. The magnet includes a plurality of magnet portions facing the plurality of teeth via a gap and are disposed in the relative movement direction. A relationship between a minimum sectional area Sc1 of one tooth end portion of the armature and a minimum sectional area Sc2 of the other tooth end portion is Sc1>Sc2; and a relationship between the minimum sectional area Sc2 of the other tooth end portion and a sectional area Sy of the yoke in a direction crossing the relative movement direction is Sc2≥Sy.
