US Patent 7110033 Imaging device having an imaging element mounted on a substrate

There is described a low-cost imaging device fixed focus type which is to be provided in a portable terminal equipment and enables easy assembly. An opening section is formed in a substrate. An imaging element is secured on the substrate such that a plane including a light-receiving surface for receiving an optical signal closes the opening section. An optical element having an imaging lens section for providing optical information is attached to the light-receiving surface. The optical element is arranged so as to come into contact with the upper surface of the imaging element by way of the opening section of the substrate.
