A positioning method positions a flexure whose front end side is joined to an outside frame with respect to a load beam, keeps the positioned state of the flexure and load beam, plastically deforms the outside frame to bend the front end side of the flexure so that the position of a tongue of the flexure is adjusted to the position of a dimple of the load beam, and joins the flexure and load beam to each other to keep the position adjusted state of the tongue.

A piezoelectric elementhas a common electrodethat receives electricity from a terminal. The terminalhas a through holeand an electric insulating layer. The piezoelectric elementis arranged so that the common electrodefaces the electric insulating layerof the terminal. A liquid stopperis formed around the through holeso as to come between the common electrodeand the terminalwhen the common electrodeand terminalare set to face each other. A liquid conductive adhesiveis injected into the through holeto fill a gap defined by the liquid stopperbetween the terminaland the common electrodeand secure electric connection between the terminaland the common electrode This configuration improves the reliability of wiring to the piezoelectric element and prevents the piezoelectric element from being damaged.
