Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To further thin a camera module by providing an imaging device mounted by a flip chip, on one side of a substrate in the state of exposing a photodetecting part from a through hole, and a lens unit mounted on the other side of the substrate in the state of covering the space above this photodetecting part.

The substrate 10, the imaging device 11 and the lens unit 12 can be more tightly located in module thickness direction. Thus, the very thin camera module 2 can be provided. Further, since the thickness of the camera module 2 is reduced, the camera module can be integrated into an information terminal while utilizing a smaller attachment space.
