摘要：
A method is provided for manufacturing a piezoelectric actuator having a piezoelectric element and a lead wire for supplying a drive signal to the piezoelectric element. A melt material is immersed into a fusing agent. A quantity of the material and the fusing agent is supplied to a transfer plate and then adjusted. A preselected quantity of the melt material and the fusing agent is then transferred preselected quantity of the melt material and the fusing agent is supplied from the transfer tool to the lead wire. The melt material is then welded on the lead wire and on the piezoelectric element to thereby connect the lead wire to the piezoelectric element.
