<p>A camera module in which a lens holder (11) 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 side and weight. To achieve this, the lens holder (11) is provided with a guide bearing section (11b), a bearing section (11a), and a piezo element holding section (11c), a guide shaft (26) is placed in parallel with the optical axis and is made to be in contact with the guide bearing section (11b), a drive shaft (27) is inserted into the bearing section (lla) so that the lens holder (11) can be moved in the direction of the optical axis along the guide shaft (26), a piezo element (20) is pressed by a securing member (13), having elastic force, against the piezo element holding section (11c) and secured in place and the drive shaft (27) receives driving force by the piezo element (20).</p> |
