摘要： A wiring connecting structure for a piezoelectric element is capable of performing wiring to the piezoelectric element without deteriorating the quality and reliability of the piezoelectric element. The piezoelectric element is arranged between a base and head of an object, to minutely move the head in a sway direction according to deformation that occurs on the piezoelectric element in response to a voltage applied from a terminal to an electrode of the piezoelectric element. The wiring connecting structure includes first and second liquid stoppers arranged between the terminal and the electrode, the second liquid stopper being arranged outside the first liquid stopper. The wiring connecting structure also includes an adhesive part to connect the electrode to the terminal. The adhesive part has a conductive adhesive part defined by the first liquid stopper and a sealing adhesive part defined by the second liquid stopper. The sealing adhesive part seals the first liquid stopper and conductive adhesive part.

摘要： A head suspension 31 has a piezoelectric element 13 that deforms in response to a voltage applied thereto, a base plate 33 having an attaching part to which the piezoelectric element 13 is attached, and a load beam 35 having a flexure 39. A front end of the load beam 35 moves in a sway direction according to the deformation of the piezoelectric element 13. The head suspension 31 includes adhesives that attach the piezoelectric element 13 to the attaching part. The adhesives are applied to and hardened at the attaching part one by one. At least one of the adhesives that is first applied to and hardened at the attaching part is electrically insulative.The head suspension 31 properly maintains electric insulation between the piezoelectric element 13 and the attaching part, sufficiently demonstrates original functions, and secures a rigidity balance and proper vibration characteristic.
