摘要： Provided are a driving apparatus and an imaging device having the driving apparatus mounted thereon, the driving apparatus being capable of performing, with a simple configuration, driving in the Z-axis direction in addition to driving in a direction along the XY plane, reducing friction at the time of driving, and performing precise position holding at the time of stop. A driving apparatus includes: a frame, a contact body supported by the frame; a holder pressed against the contact body to be supported thereby; a VCM for relatively moving the frame in a direction along a support plane formed by the contact body; and a transducer for displacing, relative to the frame, the contact body in the Z-axis direction. When driving, the transducer causes the contact body to vibrate in the Z-axis direction so as to reduce a frictional force between the contact body and the holder.
