Abstract
In a magnetic head suspension according to the present invention, each of paired right and left connecting beams that are positioned on both sides in a suspension width direction of an open section, with which piezoelectric elements are at least partially overlapped in a plan view, and connect a proximal end section directly or indirectly connected to a main actuator and a distal end section to which a load bending part is connected includes a convex portion projecting in a thickness direction that is perpendicular to the disk surface. The configuration makes it possible to improve the impact resistance and raise the resonance frequency of a magnetic head suspension capable of performing micro motion of a magnetic head slider by the piezoelectric elements.
