Magnetic head device having suspension with microactuator bonded thereto

The present invention provides a magnetic head device exhibiting a good bonded state of a piezoelectric element and a load beam, and excellent reliability. The magnetic head device includes a slider provided with a reproducing element for detecting a magnetic signal recorded on a recording medium, and a recording element for recording a magnetic signal on the recording medium, an elastic supporting member for supporting the slider, and piezoelectric elements mounted on the elastic supporting member, for distorting the elastic supporting member to change the position of the slider. The piezoelectric element and the elastic supporting member are bonded together with a photo-curing and thermosetting epoxy adhesive resin having a Young's modulus of 1 GPa or more at 25° C., and a glass transition temperature of 90° C. or more.
