According to an embodiment, a bonding strength test device measures bonding strength between a flexure of a suspension of a hard disk drive and microactuators mounted on a gimbal of the flexure. The bonding strength test device includes a clamp, dummy, and device body. The clamp fixes the flexure. The dummy is adhered to the microactuators. The probe is engaged in the dummy. The device body measures a tensile load applied to the probe while the probe is pulled toward a direction to be apart from the flexure.

A head suspensionhas a piezoelectric elementthat deforms in response to a voltage applied thereto, a base platehaving an attaching part to which the piezoelectric elementis attached, and a load beamhaving a flexure. A front end of the load beammoves in a sway direction according to the deformation of the piezoelectric element. The head suspensionincludes adhesives that attach the piezoelectric elementto 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 suspensionproperly maintains electric insulation between the piezoelectric elementand the attaching part, sufficiently demonstrates original functions, and secures a rigidity balance and proper vibration characteristic.
