Abstract:
A head gimbal assembly having a stage fixed to a head-slider. A piezoelectric element which comprises; an upper surface, a first side surface, a second side surface, a lower surface, a first electrode, a second electrode, and a gap between the first and second electrodes on the lower surface, the piezoelectric element moving the stage by extension or contraction thereof according to a voltage applied to the first and second electrodes. A transmission wiring part which has a connection pad for the piezoelectric element. A cross-connector for physically and electrically cross-connecting the first electrode and the connection pad. An adhesive fixing part which is formed from an insulating adhesive and adhesively fixes the lower surface of the piezoelectric element to the transmission wiring part, between an end of the second electrode at the gap and the cross-connector.
