Abstract
A driving apparatus comprises: an electromechanical conversion element that expands and contracts in an extending direction of a given fiducial line; a driving shaft that is fixed to one end of the electromechanical conversion element in the extending direction; a driven body that is frictionally engaged with the driving shaft; a holder that holds, through an adhesive, the electromechanical conversion element from lateral sides with respect to the extending direction; and a flange member that is provided on the driving shaft between (i) a moving region of the driven body on the driving shaft and (ii) the electromechanical conversion element.
