ABSTRACT:
A vibration actuator comprising: an electromechanical conversion element excited by a driving signal; an elastic body to which the conversion element is jointed and on a driving face of which vibration waves are generated by the excitation; and a relative moving element pressure-contacted with the driving face of the elastic body, and which is driven by the vibration waves, and wherein: a joining face of the conversion element which is joined to the elastic body has an electrode portion, and a joining strength improving portion which improves the joining strength between the elastic body and the conversion element; and the electrode portion is formed on at least one of two edge portions of the joining face, through the edge portions, an imaginary straight line pass, the line pass the improving portion and is orthogonal to a relative moving direction of the elastic body and the moving element.
