PROBLEM TO BE SOLVED: To provide a drive unit which deals with driven members having different dimensions inexpensively.SOLUTION: The drive unit includes a plurality of electromechanical conversion elements 120 which are supplied with drive power and generate mechanical vibration, a substrate 110 having a transmission line of drive power and mechanically coupled with the plurality of electromechanical conversion elements 120 in common, and an urging member 140 which makes a force, for urging each of the plurality of electromechanical conversion elements 120 toward a driven member 130, act from the substrate 110 toward the electromechanical conversion elements 120. The plurality of electromechanical conversion elements 120 are coupled to the substrate 110 at positions separated from each other in a direction for driving the driven member 130. |
