Patent ID: 8199441

Claim:
A head suspension, comprising: a piezoelectric element that deforms in response to a voltage applied thereto; a base having a fitting part with an opening to which the piezoelectric element is fitted; a load beam that is fixed to the base so that a front end of the load beam moves in a sway direction according to the deformation of the piezoelectric element; an electric insulating layer formed on the fitting part by vapor-depositing and polymerizing electrically insulative high polymer materials on the fitting part, the piezoelectric element being fitted to the fitting part through at least the electric insulating layer; and an adhesive, separately formed from the electric insulating layer, which adheres the piezoelectric element to the electric insulating layer at the fitting part; and wherein the electric insulating layer covers at least part of the fitting part at a periphery of the opening and facing the piezoelectric element, and the electric insulating layer is interposed between the fitting part and the piezoelectric element so as to transmit a distortion of the piezoelectric element to the fitting part.
