The swing-type actuator includes (a) a housing comprising a pair of yokes opposing each other and a permanent magnet attached to at least one of the yokes, for defining a magnetic gap therebetween; (b) a swingable arm having one end to which a movable coil is fixed and the other end to which a function member can be attached such that a part of the movable coil is swingable in the magnetic gap; (c) at least one platelike projection having a through-hole and integrally projecting from the swingable arm adjacent movable coil; and (d) a hold member made of a thermoplastic resin and, for the portion encompassing the part of the coil movable through the magnetic gap, having substantially the same thickness as that part of the movable coil, the hold member being molded such that it encompases the outer periphery of the movable coil and embeds the projection, thereby fixing the movable coil to the arm.
