Abstract
An imaging device having a lens group having lenses; a lens frame that holds said lens group; a base that holds said lens frame; an imaging element that has an imaging area; and a compression coil spring that prescribes the position of the lens frame relative to the imaging element so as to keep the optical axis of the lens group perpendicular to the imaging area of the imaging element. The imaging-element side of the lens frame has an orthogonal surface that is orthogonal to the optical axis of the lens group. The compression coil spring keeps said orthogonal surface in surface contact with an area that surrounds and is parallel to the imaging area of the imaging element.
