<p>A camera module and a portable terminal comprising the camera module, in which an auto-focus (AF) function and a zoom function are assembled by using a friction drive-type drive source such as a piezoelectric element, which are constructed to be small in size and light in weight, and which are resistant to chips produced through frictional contact between the piezoelectric element and a driven member. The camera module has a lens holding section for holding at least one or more optical lenses (4) and provided with a shaft hole portion, a shaft member inserted in the shaft hole portion and installed substantially in parallel with the optical axis, a piezoelectric element (10) having at an end an operation portion that is in contact with the shaft member and is placed in the vicinity of the shaft hole portion of the lens holding section, and an adhesive member (271s) provided in the vicinity of the shaft hole portion. As a result, the camera module is small in size and light in weight, and chips produced through frictional contact between the piezoelectric element (10) and the driven member are prevented from scattering by the adhesive member (271s).</p> |
