1. A lens driving apparatus, comprising:
a first fixing part;
a first movable part that includes a lens holder and is disposed so as to be separated from the first fixing part, the lens holder holding a lens part;
a first support part configured to support the first movable part with respect to the first fixing part; and
a Z-direction driving part that comprises an ultrasonic motor and moves the first movable part in a direction of an optical axis with respect to the first fixing part, the ultrasonic motor being configured to convert vibration motion into linear motion, wherein:
the lens driving apparatus further comprises a rotating body and a mechanical element, the rotating body being configured to rotate around the optical axis by receiving linear motion of the Z-direction driving part, the mechanical element being configured to convert rotational motion of the rotating body into linear motion in the direction of the optical axis,
the first movable part is configured to move in the direction of the optical axis by rotation of the rotating body, and
the lens driving apparatus further comprises:
a second movable part including the first fixing part, the first movable part, the first support part, and the Z-direction driving part;
a second fixing part disposed so as to be separated from the second movable part;
a second support part configured to support the second movable part with respect to the second fixing part; and
an XY-direction driving part configured to move the second movable part within an optical axis-orthogonal plane orthogonal to the direction of the optical axis with respect to the second fixing part.
