ABSTRACT:
A method of producing a device for magnifying displacement of a piezoelectric element adapted to be displaced by application of voltage thereto. The method includes a first step of forming a movable member integrally with a frame through a connecting portion in such a manner as a space for inserting therein a piezoelectric element is defined between the movable member and a base portion of the frame; a second step of fixing the leaf spring to the frame and the movable member; and a third step of forming a separation groove in the connecting portion to separate the movable member from the frame.
