An electromagnetic actuator includes a bobbin which is disposed between opposite ends of a housing made of a magnetic material and which has a coil wound therearound, a guide sleeve which is fitted to an inner periphery of the bobbin and which is opposed at one end thereof to one of wall ends of the housing and fitted at the other end thereof into a support bore in the other end of the housing, a stationary core fitted into the guide sleeve and caulked to the one end wall of the housing, and a movable core slidably fitted into the guide sleeve and cooperating with the stationary core. In this electromagnetic actuator, an end of the guide sleeve guiding the movable core is placed into close contact with and coupled in a caulked manner to an outer peripheral surface of the stationary core which is caulked and coupled to one of end walls of the magnetic housing. Thus, the coaxiality between the guide sleeve guiding the movable core and the stationary core can be assured despite a side thrust from the movable core.
