A lens tube has two, first and second lenses (), a tubular lens frame () for holding the two lenses (), and three spacers () in contact with the opposite lens surfaces of the first and second lenses (). The spacers () are arranged so as to be in contact with curved surfaces of the first and second lenses () and determine the distance between the first and second lenses (). The lens frame () has the same inner diameter between the first and second lenses (), and the spacers () are in contact with the inner wall of the lens frame (). Since the lens frame () has the same inner diameter between the first and second lenses (), the first and second lenses () are held with their centers perfectly aligned with each other.

Lens tube, method of assembling lens tube, and camera module

A peripheral IC 6 for a solid state imaging device is mounted on an island 7 of a lead frame and thereafter covered and sealed by a molding resin, thus forming a premolded package 2. Subsequently, a solid state image sensor 1 is mounted on the island 7 on one side thereof facing an opening. Thereafter, for protection of the solid state image sensor 1, a transparent lid 11 is attached to the premolded package 2 by adhesive. As a result, packaging area can be reduced in mounting the solid state image sensor on a packaging substrate, allowing video equipment such as video cameras to be miniaturized.
