A camera module includes a solid-state imaging device; a lens unit having a lens for guiding light to the solid-state imaging device; a lens holder for holding the solid-state imaging device, the lens holder including a lens coupling section provided for adjusting the position of the lens, such that a distance between the lens and the solid-state imaging device becomes a prescribed focusing distance; and a shield cap for covering the lens coupling section and the lens unit so as to allow the light to be guided to the lens in the lens unit.
