Abstract: A piezo-electric driving device capable of allowing a driven body to be made of a wide variety of materials and to be easily controlled with respect to speed and back-and-forth movement; comprising a plurality of piezoelectric oscillators 5, a supporter 1 for supporting the plural piezo-electric oscillators 5 arranged in parallel so that the piezo-electric oscillators 5 have the same oscillation direction, a connector 2 for mutually connecting the oscillation portions of the plural piezo-electric oscillators 5 in the direction perpendicular to the oscillation direction, and a kicking member 3 projected from the intermediate portion of the connector 2 in the oscillation direction, wherein the piezo-electric oscillators have different oscillation phases so that the kicking member 3 can perform a kicking operation.
