摘要：Problem to be solved: to provide a vibration actuator which can easily removethe feeding means when replacing the vibrator. The vibration actuator 110 includesA flatportion 1c and a projection (1a) provided on the flat plate 1CA vibrating plate 1 having a1b and aA piezoelectric element 2 fixed to a diaphragm 1 and vibratedHolding member 3

for holding diaphragm 1 andAt least a first electrode 2C and a second electrode (2a)provided on the piezoelectric element2b) andA flexible conductive sheet 5 having a widerarea than the first electrode 2C andFlexible insulating sheet 4 andAndPiezoelectricelementInsulating sheet 4The conductive sheet 5 is superimposed in order.ConductivesheetPositioned to be superimposed on at least a portion of the first electrode 2CTheinsulating sheetA second electrodeIt is characterized that the position is superimposedon all the regions in which the conductive sheet 5 is superposed.Diagram
