<p>An imaging device suitable to be built-in in a thinner portable terminal and capable of macro-imaging. An imaging device has an imaging element for photoelectrically converting object's light; an imaging optical system for guiding the object's light to the imaging element; a first lens frame for holding the imaging optical system; a second lens frame coupled to the first lens frame such that the relationship of relative position, in the optical axis direction, between the second lens frame and the first lens frame is changeable; a rotation member for changing by its rotation the position in the optical axis direction of the second lens frame; and an urging member for urging the second lens frame in the direction in which the second lens frame is in contact with the rotation member. The urging member is provided at a position on a peripheral surface of the second lens frame, on the side closer to the imaging element than that surface of the imaging optical system which is closest to the object.</p> |
