A head suspension has a base, a piezoelectric element, a load beam, and a wiring member to supply electric power to the piezoelectric element so that the piezoelectric element deforms to move the load beam relative to the base. The wiring member has a conductive base layer, an insulating layer, and a wiring layer layered in this order. The wiring layer has a wiring electrode. The piezoelectric element has an element electrode. A through hole is formed through the conductive base layer and insulating layer, to expose the wiring electrode to the element electrode. A projection is formed on at least one of the wiring electrode and element electrode, to face the other electrode through the through hole. The projection brings the electrodes into contact with each other and a conductive adhesive joins the electrodes and together.
