Abstract

In a magnetic head suspension, a piezoelectric element is disposed within a supporting part's open section so that at least a part of its distal-side end surface faces a distal-side wall surface of the supporting part's distal end section forming a distal-side gap between the distal-side end surface and the distal-side wall surface and at least a part of its proximal-side end surface faces a proximal-side wall surface of the supporting part's proximal end section forming a proximal-side gap between the proximal-side end surface and the proximal-side wall surface in a state where the piezoelectric element's upper and lower electrode layers do not face the supporting part and any rigid members that are fixed to the supporting part. The piezoelectric element is fixed to the supporting part by a distal-side insulative adhesive agent and a proximal-side insulative adhesive agent.
