Abstract:
A vibrational wave driving apparatus in the present invention includes an elastic member attached to an electromechanical energy transducing member, a pair of electrodes provided on the electromechanical energy transducing member, a wiring unit connecting the pair of electrodes and a voltage applying unit, and a driven body configured to be pressure contacted with the elastic member. The driven body is relatively driven by mechanical vibration of the elastic member generated when an alternating voltage is applied to the pair of electrodes. The wiring unit includes a pair of wiring portions connected to the pair of electrodes, respectively. The pair of wiring portions includes a pair of film-like bases and a pair of conductors formed on surfaces of the pair of film-like bases. The pair of wiring portions is arranged such that the pair of conductors overlaps each other through insulating layers.
