Claim 5:
6. An operation device comprising:
a movable part having an operating surface on which a contact operation is performed by an living body;
a vibration exciter attached to the movable part at a position other than the operating surface, and configured to excite the movable part in a first direction along the operating surface, and in a second direction intersecting the operating surface;
a base part; and
an elastic support, provided between the movable part and the base part, and configured to elastically support the movable part with respect to the base part, wherein
the movable part provides a tactile sensation to the living body making the contact operation when excited in the first direction by the vibration exciter, and generates a sound from the operating surface when excited in the second direction by the vibration exciter,
the vibration exciter includes a stator body fixed to the movable part, an elastic body connected to the stator body, and a vibrating body connected to the elastic body, and selectively vibratable in the first direction and the second direction with respect to the stator body, and
one of the stator body and the vibrating body has a coil, and the other has a magnet, and the vibrating body vibrates with respect to the stator body by a magnetic force generated between the coil and the magnet when a current is supplied to the coil.
