An operation device comprising: a movable portion including an operation member to be operated by pressing the operation member; a vibration generating unit configured to cause the movable portion to vibrate in a first direction perpendicular to a control surface of the operation member; a fixed portion supporting the movable portion via a first elastic support to allow the movable portion to vibrate; a detecting unit configured to detect that the operation member is operated by pressing the operation member; and a control unit configured to drive the vibration generating unit in accordance with a detected result by the detecting unit, wherein the vibration generating unit includes: a movable yoke attached to the movable portion; a fixed yoke attached to the fixed portion and disposed facing the movable yoke in the first direction; a permanent magnet attached to one yoke among the movable yoke and the fixed yoke, both ends of the permanent magnet in the first direction being opposite magnetic poles created by magnetization; and an exciting coil attached to a different yoke from the one yoke among the movable yoke and the fixed yoke, the exciting coil being configured to induce magnetic flux in response to a current flowing through the exciting coil, wherein, by a magnetic attractive force of the permanent magnet, the movable yoke is configured to be energized in a direction of moving closer to the fixed yoke in the first direction, wherein in an initial state in which the current is yet to flow through the exciting coil, the first elastic support is compressed between the movable portion and the fixed portion, characterised in that the current flowing through the exciting coil causes a repulsive force to act between the movable yoke and the fixed yoke, thereby making a distance between the movable yoke and the fixed yoke greater than a distance set in the initial state. a movable portion including an operation member to be operated by pressing the operation member; a vibration generating unit configured to cause the movable portion to vibrate in a first direction perpendicular to a control surface of the operation member; a fixed portion supporting the movable portion via a first elastic support to allow the movable portion to vibrate; a detecting unit configured to detect that the operation member is operated by pressing the operation member; and a control unit configured to drive the vibration generating unit in accordance with a detected result by the detecting unit, wherein the vibration generating unit includes: a movable yoke attached to the movable portion; a fixed yoke attached to the fixed portion and disposed facing the movable yoke in the first direction; a permanent magnet attached to one yoke among the movable yoke and the fixed yoke, both ends of the permanent magnet in the first direction being opposite magnetic poles created by magnetization; and an exciting coil attached to a different yoke from the one yoke among the movable yoke and the fixed yoke, the exciting coil being configured to induce magnetic flux in response to a current flowing through the exciting coil, a movable yoke attached to the movable portion; a fixed yoke attached to the fixed portion and disposed facing the movable yoke in the first direction; a permanent magnet attached to one yoke among the movable yoke and the fixed yoke, both ends of the permanent magnet in the first direction being opposite magnetic poles created by magnetization; and an exciting coil attached to a different yoke from the one yoke among the movable yoke and the fixed yoke, the exciting coil being configured to induce magnetic flux in response to a current flowing through the exciting coil, wherein, by a magnetic attractive force of the permanent magnet, the movable yoke is configured to be energized in a direction of moving closer to the fixed yoke in the first direction, wherein in an initial state in which the current is yet to flow through the exciting coil, the first elastic support is compressed between the movable portion and the fixed portion, characterised in that the current flowing through the exciting coil causes a repulsive force to act between the movable yoke and the fixed yoke, thereby making a distance between the movable yoke and the fixed yoke greater than a distance set in the initial state.
