PROBLEM TO BE SOLVED: To provide a vibration device etc., capable of efficiently moving an object including dust by vibration to a predetermined direction.SOLUTION: A vibration device includes a vibration body 3 including a plurality of electromechanical energy conversion elements 2a, 2b, 2c, and 2d, and makes the vibration body 3 generate vibrations having a first standing wave and a second standing wave, having a plurality of nodal lines lining up and differing in degree, superposed one over the other with a predetermined time phase difference. The plurality of nodal lines extend in a first direction and line up in a second direction crossing the first direction. The electromechanical energy conversion elements 2c, 2d each have a first electrode and a second electrode, which line up at intervals in the second direction; and a first nodal line as one of the plurality nodal lines is present between the first electrode and second electrode, and the second electrode is present between the first nodal line and a second nodal line adjoining the first nodal line. |
