ACTUATOR, DRIVE DEVICE, AND CAMERA MODULE

WIPO Patent Application WO/2011/040250

A1

Disclosed is a technology of accurately controlling, with a simple configuration, displacement generated in an actuator, irrespective of variance of the thickness and the qualities of thin films for controlling displacement, said variance being generated among actuators. The actuator is provided with: a reference section; and a movable section, which has a fixed section fixed to the reference section, and which has a displacement section that is displaced due to deformation that corresponds to energy applied thereto. In the actuator, the movable section has a deforming film, which is configured using a conductor material and/or a semiconductor material, and deforms corresponding to deformation of the movable section, and the reference section has a reference film that is formed using the material same as the material for the deforming film, in the same step wherein the deforming film is formed.
