PROBLEM TO BE SOLVED: To provide an inexpensive and safe piezoelectrically driven part feeder adapted to a standard of an apparatus, reducing the size and weight of a controller box, and enabling general purpose use of a controller. SOLUTION: This piezoelectrically driven part feeder has a vibrating mechanism part stored in a casing and generating vibration, and a boosting insulating transformer. The vibrating mechanism part has a plurality of bimorphs, an installation base material attached with the lower end of these bimorphs, and a carrier body attached with the upper end, arranged in the vicinity of an upper surface of the casing and carrying a carrying object. The bimorphs have a belt-like elastic plate grounded by installing a piezoelectric element on both surfaces. The boosting insulating transformer has an iron core, a primary winding having a driving terminal arranged by being exposed outside the casing, and a secondary winding having one end connected to the piezoelectric element and grounding the other end.
