ABSTRACT:
A camera module in which a lens holder that holds one or more lenses is made movable in an optical axis direction and in which an auto-focus function and a zoom function are assembled is reduced in size and weight. To achieve this, the lens holder is provided with a guide bearing section, a bearing section, and a piezo element holding section, a guide shaft is placed in parallel with the optical axis and is made to be in contact with the guide bearing section, a drive shaft is inserted into the bearing section so that the lens holder can be moved in the direction of the optical axis along the guide shaft, a piezo element is pressed by a securing member, having elastic force, against the piezoe element holding section and secured in place and the drive shaft receives driving force by the piezo element.
